I'm pretty sure that some of our players, if it isn't most of them, would be making the same choice OH, JDG2 or Vittoria made if they had the same opportunity.
I doubt the fact he played for Portugal would be too much of a big deal in the dressing room.
If he's going to play for our MNT, please don't invite him until this round is complete. It's not the time to mess with team chemistry. Then, invite him for a friendly or a camp and if he's really good (starting 11 material) then include him in the squad.
