Julian Alvarez from Atletico Madrid, Ollie Watkins from Aston Villa, Hugo Ekitike from Frankfurt and Victor Osimhen from Napoli are among the backup options.
Man United is confronted with competition from Premier League rivals for Ekitike, while the wage requirements of Osimhen are likely to stimulate a potential movement.

Wilson ended the Premier League season without a goal for his name, with a strike against Birmingham City in the FA Cup his only one of the campaign.
He had played an important role to help prevent Newcastle to prevent relegation prior to their takeover, but rejected a pay-as-you play deal to stay in the club.
Calvert-Lewin, 28, confirmed last week that he would leave Everton after nine seasons in the club where he scored 71 in 273 games.
In total, Calvert-Lewis scored 57 times in 239 Premier League matches.
