The north London club left it late but completed a deal to bring the 32-year-old Brazilian defender to The Emirates on the last day of the transfer window as Unai Emery managed to bolster his squad.
Arsenal have been broadly criticised for their failures at the back in recent seasons and Luiz will be hoping to help shore up the rearguard at The Emirates.
Chelsea FC, meanwhile, were unable to bring in a replacement for the Brazil international due to their transfer ban.
And Blues legend Zola believes that the signing of Luiz from Chelsea FC represents an excellent piece of business from Arsenal.
Speaking in an interview quoted by Metro, 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.”
Chelsea FC will return to action on Wednesday night when they travel to Istanbul to take on Liverpool FC in the Uefa Super Cup.
Arsenal, meanwhile, will return to Premier League action on Saturday lunchtime when they host Burnley at The Emirates.
The Gunners are aiming to try and break back into the top four after having finished fifth last term.
