Vinagre is almost certain to replace the injured Jonny Castro Otto at left wing-back, with the Spain international set to be sidelined for up to six weeks.

Teenager Vinagre's last league start came almost a year ago but he's made four appearance from the bench in the Premier League and won the Euro U19 Championship with Portugal in the summer.

"He's ready to go, he's matured," Nuno said.

"Last season he had his chance, at the beginning of this season he wasn't with us as he was becoming a European champion.

"He's growing, he's getting better. I'm totally confident that the answer's going to be good.

"It's more than the title, it's the high level of competition he was involved in.

"They won the competition and he improved a lot."
