According to the Dutch news outlet, Chelsea and Ajax have agreed on a summer transfer deal for the highly-rated 23-year-old keeper.

While the Tier 2 source doesn’t elaborate on the details of the deal, it is believed the Blues will have to cough up £40-50 million for the Cameroonian.

The 16-cap Cameroonian international started his footballing education at the Samuel Eto’o foundation in his homeland before joining Barcelona’s youth system in 2010.

Onana spent five years at La Masia but lack of first-team opportunities prompted him to move across the continent to join Ajax back in 2015.

After impressing for the reserve team in the Dutch second-tier, the shot-stopper eventually made his senior breakthrough in the Eredivisie during the 2016-17 campaign and he hasn’t looked back since then.

His overall record at Ajax looks very impressive, indeed. Onana has shipped 151 goals in 171 games for the Dutch giants, keeping 72 clean sheets in the process, and his tender years mean that he is only going to get better with time.

Onana will reportedly come to replace faltering Kepa Arrizabalaga. The Spaniard has been demoted back to the bench and Frank Lampard has even tried playing Willy Caballero instead.
