Arsenal hero Emmanuel Petit says Philippe Coutinho must regret leaving Liverpool for Barcelona.

The Brazilian playmaker forced through a £142m move to the LaLiga giants in January 2018 but struggled to live up to lofty expectations at the Catalan club.

Petit said: "If I was Philippe Coutinho, every morning I would wake up and think to myself, 'Why, why, did I sign [for Barcelona] in Spain?'

"And do you know why I say this? Because, I can remember the time when I'd wake up, when I was at Barcelona, when I left Arsenal, and I was thinking the same way, 'Why did I leave? Why did I leave? Why did I leave?'

"To be honest with you I am sure Coutinho has been asking himself the same question for a while now.

"He left for Bayern Munich, he does sometimes play well but he's not really a first-team player."
