The Old Trafford club will pay £43.8 million upfront for the Cameroon international, with an extra £3.4 million in add-ons.

United hope he will be able to join them on their next tour of the United States, but he will need to obtain a visa.

Erik ten Hag, the manager, signed the keeper at the end of the season after previously working with him at Ajax.

He’ll be on a five-year deal with a sixth year option.

Ten Hag believes Onana may be a valuable addition to United’s squad, and his search for a new goalkeeper forced David de Gea to decline a new contract offer.

De Gea has been United’s first-choice goalkeeper for the past 12 years, appearing in 545 games since joining the club under Sir Alex Ferguson.

The Spaniard holds the club record for clean sheets with 190.

Onana spent seven and a half years with Ajax before joining Inter on a free transfer in July 2022.

He kept eight clean sheets in 24 Serie A games as Inter finished third, and no club scored past him in 13 Champions League matches last season, the most of any goalie in the competition.

In June, he appeared in the Champions League final against Manchester City, which Inter lost 1-0.
