Everton boss Carlo Ancelotti insists he can still improve despite being one of the most successful manager's of all time.

The Italian has won titles in England, Spain, Italy, Germany and France, as well as three Champions League crowns.

Speaking to the club's website, the 61-year-old: "You can improve, personally, and you have to improve.

"Football is changing, it changed a lot in the past and will change a lot in future.

"There are a lot of situations where you can get better and it is the same for the squad.

"After the game, you think about everything that happened on the pitch, the substitutions, what you could do and didn't do – what you did well.

"This is a discussion you need to have with your staff.

"But not immediately after the game because you are too hot.

"The adrenaline stays in my body a long time, at least 12 hours more [following full-time].

"If the game was tough and exciting – like Tottenham [5-4 win in FA Cup] – for example, the night after, for me, is really difficult to sleep.

"I stay awake a long time.

"You have to wait a little bit – the day after you can have the right discussion with the staff about what happened."
