Arsenal legend Martin Keown was baffled by the club's decision to hand David Luiz a new deal after his horror show against Manchester City.
Luiz gave away a penalty and was sent off in the Gunners' 3-1 loss to the Citizens just over a week ago, with some feeling he may have played his last game for the club.
However, the Brazilian was one of four players to get a contract extension this week but Keown, who won three Premier League titles, feels the defender should have been released.
“What I’m concerned about now is the stock of the manager,” he told talkSPORT.
“I think there’s enough favour there for Arteta as a young manager to maybe get away with this one.
“Nonetheless, I think he should be making the right decisions for the football club and I don’t believe David Luiz is the right man to be in that dressing room.
“Frank Lampard took a different view when he took over at Chelsea; he wanted David Luiz out of his dressing room, for whatever reason, whether that was performance or character, I’m not sure, but he made that clear decision.”

“Now, I think David Luiz is very lucky to be there back at Arsenal for another year.
“But then I worry about the manager, because you only get so long in this job and you’ve got to make the right decisions, and the early decisions have to be right.
“That is a huge problem, that position; David Luiz has given the most penalties away this season, four, he’s not mobile enough, he goes to ground too early…
“As former players we don’t enjoy ridiculing and hammering players, and he’s had a fine career, but he’s only ever done it in a back-three.
