But the 6ft 4ins centre-back, a £27million signing 12 months ago, admits he still has much to learn about the Premier League and his partnership with Keane will be key.

All of Mina's five Everton clean sheets, three of which have been in his last four appearances dating back to March, have come when starting alongside the former Burnley player in a back four.

"I feel very good, the manager (Marco Silva) is working with me every day and giving me a lot of confidence," Mina, who has not started more than six successive matches because of injury problems, told evertonfc.com.

"I am understanding more what he wants all the time and becoming more comfortable.

"This is my best football since I came to Everton but I have to keep my focus and always work to improve.

"It is the main job of the goalkeeper and centre-backs to keep clean sheets – that is what we are working to achieve every day.

"But we know there is still much to improve."
