He had a very poor game today, it happens with younger players especially.
The fact he hasn't been able to consistently settle in the one position can't help him though. He looks better suited as a centre-back for sure, and with experience am sure he'll cut out the silly errors (meaning going to ground against attackers instead of staying on his feet).
When he first came to us though, people who knew more about football than me rated him highly, remember him being mentioned as another John Stones coming through.
Maybe he could do with a loan spell in the Championship, IF we get centre-back cover in January? We'll have Seamus back soon enough, so right fullback will be well covered with him, Kenny and Martina.
