Do Manchester United need a number nine?published at 14:28 British Summer Time

United scored a record low of 44 goals in 38 Premier League matches last season, therefore a new number nine at Old Trafford has been one of the big talking points this summer.
If they don't bring one in, what could happen?
Could existing strikers Rasmus Hojlund or Joshua Zirkzee benefit from having both Matheus Cunha and Bryan Mbeumo around them?
Or could one of the new arrivals, despite not being out-and-out strikers, be deployed up there?
