Arsenal head coach Unai Emery has revealed he is impressed with how Sokratis Papastathopoulos has adaptated to English football.
The Gunners boss is counting on the 30-year-old, who joined from Borussia Dortmund at the start of the season after a five-year spell at Signal Iduna Park, in Thursday's Europa League quarter-final second leg against Napoli.
However, Emery says he is “very happy” with the Greece centre-back’s “experience” and physical presence.
"I think the adaptation [at] first is important and not easy," Emery told reporters in his pre-match news conference.
"It's different for different players. We spoke about that with Papa [Sokratis] 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 [Thursday] is a big match, so we need players with experience. He's one of those players."
