"They're fantastic signings for the club," Robinson told reporters. "I'm absolutely delighted to get those two on board, especially now with a couple of months to go till the end of the season because it's important. It's important for them to get to grips with what it's like being a MLS professional, getting used to the environment for January when they come because it's the progression I want as the manager of the club as well as what the club want.
"I think it's important for the growth of this club that we see players coming through regularly. Not just one year, every three or four years, but every year. They're added to our already talented young pool of players that we've got. I'm delighted to have them both on board."
It's a delight matched by both players, as they grinned from ear to ear throughout their first media scrums as pros. So now that they've had a small amount of time for it to all sunk in, how does it feel to have signed their first pro contracts?
"[Monday] was an amazing day really," Froese told us. "It's surreal to say the least. It's a dream come true but the work starts now."
That was a view echoed by Bustos, although it's their hard work already in the Residency program that has seen them earn their pro deals at 18-years-old. But now that the pair have that MLS contract, neither is going to be resting on his laurels.
"It's a good feeling because I've pretty much put the weight off my shoulders for how hard I've worked for the past 10, 12 months," Bustos told us. "To know that I've got myself in the team for next season is a good step for me because that then pushes me to fight for a spot on the squad. That realistically, at the end of the day, I want to be in the 18 man squad and sooner, rather than later, be in the 11 man squad."
Both players have impressed at training this year and they got an initial reward back in May when they started the first leg of the Canadian Championship semi-final in Toronto. Although a spot in the second leg was deprived of them due to a Canadian national team training camp, the experience that both got in that game against TFC gave them a taste of playing for the Whitecaps first team and left them knowing they could perform at that level and wanting more.
"The experience leaves me with the thought that I can be here and I could play with the squad," Bustos said. "It makes me believe that I can get in the 11 man squad and it shows me that the coaches believe in me. Whenever the coaches give me the chance to get out on the field again, then I'll hopefully take that chance and give them everything."
Froese agrees and the match helped them realise that they've arrived in football and are playing with and against world class players now.
"When I saw [Michael] Bradley playing in the World Cup, I was like, 'yeah, I've played against him'!," Froese joked. "Obviously it just shows that we can do it and we can hopefully play, so it just gives us confidence to go and do it when the chance comes."
And Froese may be getting that chance in the very near future. With six games remaining, Robinson has no qualms about pitching the young star into the mix, whether the Whitecaps are in the heat of a playoff battle or not, and the 'Caps coach has no doubts that he's already capable of playing at MLS level.
"Kianz is very much in contention," Robinson replied when asked if Froese would only play if the Caps were out of the playoffs. "We don't need to be eliminated or out of it for him to get the opportunity. I think you see today in training what he brings.
"We know there's areas of his game that need a little bit more focus. I just spoke to him at length about what we're going to do in the offseason, but he's very much in the picture between now and the end of the season. And rightly so, because his performances and his training have fully deserved that. So don't be surprised if you see him soon."
Signing a MLS contract is already a dream come to true for Froese, but to then play right away and have the chance to shape the club's playoff hopes is taking it to another level altogether, but one he's excited at the prospect of and ready for.
"That would be unreal," Froese said. "That's my goal for right now. To hopefully get to go on a trip with the team and just be a part of the team and help in any way I can. Obviously that's earned on the field, so right now I'm just focussing on staying consistent and hopefully I get a chance."
Unfortunately, Marco Bustos won't get his chance to shine this season, having only signed a pre-contract for MLS that won't kick in until January next year.
It's disappointing, especially with the top form that he is in right now with the Residency, but taking the long term view, this may see him signing a Generation Adidas deal with Russell Teibert moving off his. And in light of Major League Soccer's weird roster rules at the best of times, the Whitecaps didn't want to take any chances.
"As you know, with the expansion draft coming up, it's a tricky time for all MLS clubs," Robinson told us. "With the protection rule of only ten players, maybe bumping two of them up at a certain time will give the possibility of me maybe losing one or two players and I don't want to do that at this time because I'm building here.
"I can get one of them on the roster, which is why I think Kianz is slightly more ready than Marco, even though Marco scored five goals on the weekend and beat six men to get his goal of the season contender."
And what a goal that was. If anyone needed convincing of the talent Bustos has and what he offers the Whitecaps, they should have seen his second goal against San Juan on Sunday. It may have been at youth level but he picked the ball up 40 yards from goal and weaved his way past six players before coolly putting it away past the keeper. Has he scored a better goal than that?
"I can't remember all the goals I've scored, but I think that's probably one of the best ones I've scored for the Whitecaps Residency," Bustos said. "Going through those bunch of guys and finishing was pretty cool."
Bustos hit a hat-trick in Saturday's 3-2 win for the Whitecaps U18s over Seattle and followed that up with a brace against San Juan. With the minutes ticking down he had the chance to hit back to back hat-tricks, but could only look on as his shot cannoned off the left hand post.
"It would have been nice to get the two hat-tricks but at the end of the day we won the game, so that's all that matters to me," Bustos told us when we ask him if he was disappointed at missing out on an impressive feat.
Bustos has been given the captain's armband for the U18s this season and the attitude and knowledge sharing he has shown since training with the first team, played an important part in the decision to reward him with a MLS contract. The Whitecaps are always keen to see how the young players react when they go back into the Residency environment and Bustos' attitude has been exemplary. So how did the captaincy come about?
"The two Residency coaches, Steve Meadley and Niall Thompson, had pulled me aside at the end of last season and asked me if I would take the honour of being the skipper," Bustos told us. "They talked to me a little bit about trying to build my leadership to make myself a better pro and I wanted to take the challenge.
"Just to have that extra leadership skill in me and to lead by example and lead vocally, I think will make me a better player, so I wanted to take that opportunity to make myself better."
He has already been leading by example, and not just with his five goals on the opening weekend, but Bustos hopes that he and his good friend, and fellow Manitoba boy, Froese can be good role models for other Canadian kids looking to make it in the pro ranks.
"Knowing that me and Kianz have made it here will hopefully inspire other young kids to follow their dreams and to go forward and hopefully one day they could follow our footsteps," Bustos added.
With more Residency homegrown talent on the horizon and pushing hard, I don't think he'll have to wait too long for that.
