It is understood the Slovenian striker has already agreed personal terms over a proposed move to Old Trafford after he made it clear he preferred a move to Manchester over Newcastle. All that is left is for United to agree on a financial package with Leipzig over his transfer, before Sesko will be allowed to undergo a medical.
Ruben Amorim made it a priority to add a striker to his first-team squad even after he had been backed with both Bryan Mbeumo and Matheus Cunha. It means United could spend just over £200 million on three new attacking additions as they look to address the goal scoring issues that plagued them so much last season.
There is now a welcome selection headache to solve and here is what we think United's strongest line up will be once Sesko signs.
Onana is the best goalkeeper at the club and won't be replaced this summer.
