Ole Gunnar Solskjaer is desperate to rebuild his squad before the new season. The Red Devils finished 6th in the Premier League and missed out on lucrative Champions League football. Talented youngster Daniel James is the only signing to arrive at Old Trafford so far, having joined United from Championship side Swansea City for £18 million.
United have identified an ageing defence as a glaring weakness and are also in the running to sign England international Harry Maguire, although they face a bidding war with derby rivals Manchester City.
Wan-Bissaka is eager to complete a move to Manchester before the start of next season. The Red Devils are prepared to break the bank and spend at least £60 million on the Palace right-back.
