Manchester United would face making up a substantial gap if they are to successfully swap Alejandro Garnacho for Nicolas Jackson this summer, due to Chelsea's vast difference in valuations of the pair.
The Red Devils are seeking to offload Garnacho this summer, with the Argentine international one of the unwanted players placed into a 'bomb squad'.
Garnacho was told by Man United boss Ruben Amorim to find a new club in May, after the winger was unhappy to start on the bench in the Europa League final.
