Former Chelsea boss Ruud Gullit has taken aim at Arsenal defender David Luiz.
The Brazilian's time at the Emirates could be drawing to a close, with his contract due to expire at the end of the month.
"Yes, David is not doing well," Gullit told Ziggo Sport.
"I think he's an overrated player, really. When he played in midfield I thought he was reasonable, but then there was already discussion about what he actually is as a player.
"But he preferred to play as a defender… Well, we all remember the match between Brazil and Germany (7-1 at the 2014 World Cup). I just can't understand it!
"Most clubs have done away with him, but he keeps coming back somewhere."
