If Manchester United go through with the loan signing of Ousmane Dembele, they'll be acquiring a player whose speed and two-footed talent make him unplayable when he is at his best.
But they would also be getting someone whose dreadful luck with injuries make him a massive gamble.
United need a forward and Barcelona have a surplus. Dembele is the one they would be happiest to lose – his three years at the club have so far have been a financial embarrassment for them and an endless slog of set-backs for him.
