Arsenal manager Unai Emery has praised the way that summer signing Sokratis Papasthathopoulos has been able to adapt to life in England following his move to the Gunners at the start of the season.
The Gunners boss lauded the impact of the Greek international on the Arsenal team during his pre-match press conference ahead of the Napoli game in the Europa League.
Sokratis Papasthathopoulos signed for Arsenal last summer after the Gunners paid around £17m for his signature.
The Greek centre back joined Arsenal from German Bundesliga club Borussia Dortmund and he has been a key player for the North Londoners since his transfer last summer.
Sokratis will return to the Arsenal starting XI for the away game at Napoli in the Europa League after he missed the league match at Watford on Monday night.
He was banned for two Premier League games after accruing ten yellow cards since the start of the season.
The Greek defender missed the 1-0 win over the Hornets and will also sit out the home game against London rivals Crystal Palace.
Sokratis and Arsenal take a 2-0 lead to Naples from the first leg.
A 15th-minute strike from Welsh international Aaron Ramsey and an own goal from Kalidou Koulibaly gave the Gunners a comfortable advantage ahead of the second leg on Thursday night.
