After he made his full debut at Old Trafford today, Arsene Wenger says that Konstantinos Mavropanos surprised people with the level of performance he put in, even though the Gunners went down 2-1.

The 20 year old was handed his first Arsenal start and under difficult circumstances played very well, and along with Calum Chambers he formed an interesting central defensive partnership.

He was signed for £2m from PAS Giannina in January with the idea of going straight out on loan, but the Arsenal boss decided to keep him having seen how well he performed in training.

Speaking after the game, Wenger said, “In training he has shown top quality but then you always have a question mark as long as you don’t see that under pressure in a big game.

“Until that, you don’t know. The big players do better in the competition than in training.

“They make a career, the others – we have many players at our level who do less well in competition than in training.

“That was the question mark and I think he did well. He surprised everybody by his quality today.”

It remains to be seen how much more he’ll play this season, that will, of course, be dependent on how far we go in Europe.

If we do manage to reach the Europa League final, he could well get more chances.
