Manchester United have made a third bid for Brentford forward Bryan Mbeumo that could be worth up to £70m.
The offer is understood to be an initial £65m, with £5m in add-ons.
Brentford are yet to respond to the offer.
United have remained confident about getting Mbeumo and had been hopeful of adding the Cameroon international to Ruben Amorim’s squad before they head to the US on Tuesday for three pre-season games.
Although United have been strongly linked with Chelsea forward Nicolas Jackson and Aston Villa goalkeeper Emiliano Martinez in recent days, it has always been the priority at Old Trafford to get the Mbeumo deal done in time for Amorim to work with him in the Chicago, where United will largely be based for their 13-day trip.
The 25-year-old scored 20 Premier League goals last season and a number of clubs were interested in him, including Tottenham, now managed by former Brentford boss Thomas Frank.
However, Mbeumo’s preference was to join United.
