Dinos Mavropanos has received glowing praise from Arsenal teammate Sokratis.
Injury has ruined the 21-year-old's campaign after showing promise following his £2 million move from Pas Giannina in January.
And Sokratis, who has taken his compatriot under his wing, says Mavropanos has potential to become a star.
''Dinos can become much better than me and it will be bad for him to have Papastathopoulos as a ceiling," said the 30-year-old.
"I am telling you that Mavropanos has all the assets to become better than Papastathopoulos."
