Middlesbrough attacker Adama Traore has taken a swipe at former club Barcelona.

There's now regret at Barca over letting Adama to leave last year.

"I did not leave Barcelona in a positive way. I left because I did not get the chance. Had I been given a single chance I might have been able to say what I was missing," he told El Mundo Deportivo.

"They gave me no explanation. They made me stay in Barcelona B and I asked them to just let me show that I measure up.

"No-one talked to me. I wanted an explanation."
