The agreement includes a guaranteed payment of £66.3m (76.5m euros) with the remainder in add-ons.

Sesko will now complete the formalities, including undergoing a medical on Friday, before finalising his move to Old Trafford.

The 22-year-old Slovenia forward, who was also wanted by Newcastle, has scored 39 goals in 87 appearances for German side Leipzig.

United have aready signed forwards Matheus Cunha and Bryan Mbeumo this summer for a combined fee of about £130m.

Those payments have been arranged in a favourable way to allow United to keep spending, while the entirety of Marcus Rashford's £325,000-a-week salary is being covered by his loan move to Barcelona.

United also received £5m from Chelsea after the Blues pulled out of a deal to sign Jadon Sancho.

And United want a further £50m for Argentine winger Alejandro Garnacho, who is attracting interest from Chelsea and has been told he can leave Old Trafford this summer.

Their main striker from last season, Rasmus Hojlund, has been made available for sale for £40m after scoring just 14 Premier League goals in two seasons.

Sesko's decision to move to Old Trafford is a further blow to Newcastle, who missed out on Hugo Ekitike to Liverpool and face seeing their main striker Alexander Isak potentially join him at Anfield.
