David Luiz left Chelsea for Arsenal on transfer deadline day for a fee believed to be around £8 million.
Chelsea legend Gianfranco Zola is surprised the club let Luiz join Arsenal because he believes Luiz will strengthen Arsenal.
Zola worked as Maurizio Sarri’s assistant at Chelsea last season and he believes Luiz is a leader in the dressing room.
Speaking on beINSPORTS, Zola said: “It’s certainly good business for Arsenal because they are acquiring a player with a lot of personality, a lot of influence, and seeing the type of team that Arsenal are, it will be very beneficial for them.
“He has big influence with the other players. He is a leader, he definitely is a leader. He always gets the attention of the others. He’s a very intelligent player and person and so the others listen to him.
“Last year, for example, he was very important for players like [Antonio] Rudiger, they were always looking up to him, especially for a team that is trying to play football from the back – like we were, and like Arsenal are.
“It’s very important to have somebody who takes responsibility when he plays, very important.
“I don’t think there is anybody as good as him in breaking the lines from the back. He gets on the ball, he’s always got this passing in between the lines, or switching the play, he can make a big difference. For us, last year, he was very important.
“Considering what Arsenal need, it’s a brilliant move because he’s exactly the type of player they need.”
Asked if Luiz was the kind of player that would guide his centre-back partners, Zola continued: “Absolutely. My first reaction was that something must have happened in the changing room because I couldn’t see him leaving the club.
“They always gave him a big value for what he did in the changing room. [Gary] Cahill leaving was another one, another big voice, I didn’t expect him to leave.”
