No disrespect to him but playing half an hour of extra time on the wing against a team who’ve just played 90 minutes, is so far away from starting as a left back, it’s untrue.
It isn’t about trust, it’s about reality. When he’s ready, he’ll get a chance. If he’s never ready, he’ll be moved on.
If he thinks he’s ready but the club doesn’t then he’ll be on his 4th club by 20 which probably starts to raise alarms with the big teams in the big leagues.
That said, if that happens, in 7 years time when he’s playing mid table Serie A, I’ll enjoy the ‘we got rid of him too early’ chat.
However, I hope he sticks with it, keeps progressing and gets a go either later this season or early next with us.
