Arsenal manager Mikel Arteta has no fears about taking on former Gunner Sokratis in the Europa League.
The Greek international left Arsenal earlier this season, after being excluded from their Premier League squad for the term.
While Arteta was complimentary of Sokratis, he said the centre-back did not know any secrets that could hurt the Gunners on Thursday.
Arteta told reporters: "Papa is such a good character and a very popular player here.
"He was liked and loved by everybody and it was a pleasure to work with him.
"He's such a pro and he knows what we try to do, but there isn't a magic formula and I'm sure he will try to do his best.
"We will do the same."
