Visits to Brentford are difficult enough for Manchester United these days without the bad blood that will give Saturday's lunchtime clash at the Gtech Community Stadium an extra edge.
The occasion will see Bryan Mbeumo’s return to his old club and the first meeting between United and Brentford since they fell out over his £71million move to Old Trafford in the summer.
United accused Brentford of dragging out negotiations by ramping up their valuation from £70m to £77m, while putting pressure on Mbeumo to drop his personal terms to make the deal go through - or consider joining Tottenham or Newcastle instead.
