Cape Town - Manchester United are concerned their interest in Crystal Palace full-back Aaron Wan-Bissaka could be scuppered by his team-mate and former Red Devil, Wilfried Zaha.
And that could yet see the door opened to rivals Manchester City, who increasingly see the talented Eagles' right-back as an attractive long-term alternative to Kyle Walker.
Old Trafford chiefs have made signing 21-year-old Wan-Bissaka a priority signing this summer for Ole Gunnar Solskjaer, with a major squad revamp being planned.
However, United, who believe a £50 million offer can seal the deal, are concerned with the reports now linking Zaha with a move away from Selhurst Park.
The Ivory Coast winger wants to try his luck again at a top club, having previously flopped badly during a miserable two-year spell with the Red Devils.
United do have a future sell-on clause on Zaha, but that will be small consolation if it means they miss out on Wan-Bissaka.
There is increased fear inside the Theatre of Dreams that Palace will not sanction the sale of their two best players - especially if a club meets with Zaha's huge £80 million valuation.
