Chelsea boss Graham Potter insists Manchester City's interest Marc Cucurella is proof enough of the Spaniard's quality.

While Brighton manager, Potter spent much of his summer wondering whether Cucurella would join Pep Guardiola at Man City before seeing Chelsea outbid them late on in the process.

He said that Guardiola's judgement of his player deserves some weight: “If you do any research about Marc in Spain the character was fantastic.

“The team that was interested in him [Man City], I don't think they'd be interested if he didn't have the character he has.

“Chelsea weren't the only team that wanted to buy him. The other team that wanted to buy him were quite good.

“The club invested a lot of money in him in the summer. I was at Brighton last year so I know his qualities. He was the final piece, I would say, in our puzzle. He helped the team to function really well.

“At Chelsea, with the amount of transition there is, is a really different situation. It won't be the first time that in the first six months at a club that it doesn't feel like it should. It can affect your performance.

“I think Marc is a big boy, he is an adult who has got kids. He knows the situation. We have to help him to change perspectives on this."
