Onana’s debut campaign after completing a £47.2m move from Inter Milan last summer was scarred by mistakes.

They proved costly as United exited the Champions League at the group stage and raised questions of manager Erik ten Hag, who had released four-time club player of the year David de Gea in order to bring the Cameroon international to the club.

Onana improved after the African Cup of Nations, although he was blamed by some for what proved to be Manchester City’s consolation goal in the FA Cup final last May.

“Last year will help, 100%,” said the 28-year-old from United's pre-season training camp in the United States. “When you move to a new country some people need time to feel good and play good.

“Mistakes are part of life. Who doesn’t make mistakes? I am old enough to accept this kind of responsibility.

“This club is one of the biggest in the world and you need a lot of personality and character to play here and that is what you have to show on the pitch.”
