For several reasons,
I think he is good enough and deserves to start.
Not starting games , when he is part of the first team squad, MAY, affect his confidence levels.
Fitness levels, being match fit and ready to play at the highest levels, you need to play, or it takes weeks to get To that fitness.
Guardiola has sat next to him in press conferences , telling everyone how good he is and is ready to start, late September now and he should be back at School.
The performance at home to Spurs showed he will not be a hindrance.
I never pick a team on pre match threads as the coach knows how they are regards fitness, injury, mentality etc, but I thought he would have started by now, hence my post.
I take it you are not at all surprised he has not played.
