Arsenal boss Unai Emery admits he's delighted with the progress of Sokratis this season.
The defender has been impressive since his summer arrival from Borussia Dortmund.
Ahead of their Europa League clash at Napoli, Emery said, "I have the confidence in every player. In this moment, every player wants to play, wants to help us, the behaviour is very good every day, the commitment to work and to be ready is fantastic. All the players that we have ready to play, like Papa because he was suspended in the Premier League, their commitment is fantastic.
"I think the adaptation first is important and not easy. It's different for different players. We spoke about that with Papa in pre-season. His adaptation was with the time and the training, the matches are different in England. He took the big performances to help us like he is now. We are very happy with him and tomorrow is a big match so we need players with experience. He's one of those players."
