Absolutely!!!!!.... Technically, there is still a chance he can choose to play for Chile, albeit fair (however you wanna look at it), so I also wouldn't rule down that possibility at this point!!!!!... Some strong performances, even as a sub or as you said, if he can be accommodated as a starter in another area of the field or provide serious competition to Adnan, I do not see why !!!!
The fact he is signed to a team based here + will be/is expected to play there permanently for the next couple of seasons should bode well for our chances in him leaning to us + being far more visible/accessible to CANMNT staff/scouts, however
Again, as you mentioned in another post there are already a fair number of Conmebol international plying their trade in MLS, particularly from the FAs that are not considered to be the juggernauts.... Chile is not Argentina/Brazil or even Uruguay to overlook MLS talent/regulars... The latter, though, still have some players playing regular youth fútbol from them (Diego Rossi is playing olympic qualifier at this time for Uruguay for instance)
You forgot to mention that now Perú has become another Conmebol country with heavy representation in MLS (they have a fair number of national team players there as well)😉....... Chile is at around par with them....
