FFP could mean Man United can't afford Inter's Onana

Things appear to remain complicated for Manchester United. After the club appear to have let veteran goalkeeper David De Gea walk when his contract expired on Saturday, their plan A replacement seems to now be out of reach.
'Daily Mail' reported on Friday that Inter were waiting for contact from United over their keeper Andre Onana, who has been linked as a priority target for the Red Devils, but no official bid has been made yet.
Inter would be happy to sell Onana, who would fetch them a handy profit after he joined on a free, so they could put the almost €70 million he would earn to their own signings. The same outlet reports that United representatives have met with the player's agent to discuss the move.
However, 'Mirror Football' report that United wouldn't have the money to secure Onana. After agreeing a deal of similar value for Chelsea's Mason Mount, the outlet claims that Financial Fair Play rules would mean that United would need to sell a number of players before they could hope to sign the Cameroonian international. But they aren't the only ones interested, and he may be sold before they raise the funds.
The Manchester outfit are reportedly now looking at Feyenoord’s Justin Bijlow and Eintracht Frankfurt’s Kevin Trapp as cheaper replacements to solve the issue.
