Arsenal will face Olympiacos in the last 16 of the Europa League after the draw was done on Friday afternoon.
Sokratis Papastathopoulos will be able to face his former club Arsenal after he left the north London side for Olympiacos on a free transfer in January. And now the defender, who spent nearly three years with the Gunners is confident his new club can exploit Arsenal's weak points when the two sides meet.
"It is something special because until a month ago I was with them. I think it will be a difficult game. Arsenal are a very big team," said the defender.
"We have to be focused during both games to repeat last year."
"There are no big differences because he is the same coach. More or less it is the same team with two or three additions. It is a team with great quality, but there are also areas we can hit to harm them."
The north London side will travel to Greece on March 11 to face Olympiacos for the first leg of their Europa League tie.
