Arsenal should not sign David Luiz on transfer deadline day, according to former Gunners defender Martin Keown.
The Brazilian is primed to complete an £8million switch across London from Chelsea before the window closes at 5pm on Thursday, with Celtic defender Kieran Tierney also set to join him at the Emirates Stadium.
But Keown - who won three Premier League titles and three FA Cups during two separate spells at the Gunners totalling 13 years - doesn't think that the 32-year-old would be a good fit for Unai Emery's side, who lost Laurent Koscielny to Bordeaux earlier this week.
"If I was at Arsenal and had the ear of Unai Emery, I would be advising my manager not to sign David Luiz," former defender Keown told the Mail Online .
"Walk away from this deal. This is not the defender for you. It’s too high risk.
"Yes, Arsenal want a centre back, but is Luiz the answer to their prayers? I don’t think so.
"The way the 32-year-old plays, he would be exposed in that Arsenal defence. He would not get the same protection that he enjoys at Chelsea , where N’Golo Kante patrols in front of the back line.
"In possession, Luiz is a wonderful passer, but he makes mistakes when playing as part of a back four.
"He has a tendency to lose his marker and is one of those all-or-nothing players — if he doesn’t win the ball in a challenge, then congratulations because you’re in."
Luiz is set to become the 10th player to represent both Chelsea and Arsenal in the Premier League, and he could make his debut in the Gunners' Premier League opener at Newcastle United on Sunday.
