Former Olympique Marseille coach Rolland Courbis has questioned whether Unai Emery can handle the Arsenal job.
Courbis believes PSG was too big a challenge for the Basque.
He told RMC: "Thomas Tuchel is not necessarily faultless but I find him really nice. And it's not a question of a new coach. If I put myself in the place of a player and you ask me the question, I prefer to be trained by Tuchel.
"Emery made a lot of mistakes with this squad. He is a conscientious man professionally but you will not get rid of the idea that PSG was too big for him. Now we will see him in another context at Arsenal and we will follow him with a lot of sympathy and curiosity."
