Former Manchester United coach Rene Meulensteen says they need to buy a new centre-forward this summer.
Meulensteen is unconvinced about Odion Ighalo.
He told talkSPORT, “They brought Ighalo in as a player who could help United in certain times and he's actually done very, very well. But if you look at the other players there – Rashford, Martial, they're not really out-and-out strikers.
“Greenwood, a young player coming up, it's the same thing there.
“A lot of chances and goals can be created from the wide areas, Sancho is actually the same player.
“What I think Man United are missing is a striker of the calibre of Robert Lewandowski.
“Somebody up there who can hold the line, link play, but when it comes to finishing chances in and outside the box, that sort of player, they are hard to come by.
“Fifty million for Sancho, is that too much? For me, looking at what United have in those wide areas, is that where you want to strengthen?"
