Chelsea annoyed Manchester United by playing Marc Cucurella in the Carabao Cup during transfer negotiations over the summer, according to Fabrizio Romano.
The Red Devils went into the transfer market towards the end of the window in an attempt to find left-back cover after Luke Shaw suffered an injury.
Tyrell Malacia is yet to play this season as he recovers from an injury and Shaw has picked up a muscular issue that could keep him out for a couple of months.
That saw Man Utd target Chelsea left-back Cucurella on a season-long loan deal before a deal eventually broke down and the Red Devils moved to sign Tottenham’s Sergio Reguilon instead.
And transfer expert Romano insists Man Utd were left “unhappy with Chelsea” after they cup-tied Cucurella during transfer negotiations.
Romano wrote in his Caught Offside column: “There was some bad news between Manchester United and Marc Cucurella, as I’m sure fans have heard. The loan deal for the Chelsea player was close to being completed but completely fell apart, despite both sides being keen on closing this deal.
“Chelsea and the player weren’t happy with a break clause that would mean the loan would only be a temporary solution for United and would come to an end in January, conveniently in time for injured players at Manchester United, notably Luke Shaw and Tyrell Malacia, to return to the pitch.
“United were also unhappy with Chelsea playing Cucurella in the Carabao Cup, which means he’s cup-tied in the competition.
“Interest in the fullback didn’t end there, with Fulham also attempting to agree a loan move for the former Brighton player on deadline day after the deal failed to work out between United and Chelsea, but the player preferred to remain at Stamford Bridge.
“He wants to fight for his place. But keep an eye on this player guys, as there was interest expressed by a number of European clubs – including RB Leipzig, Sevilla and Real Sociedad – not to mention Manchester City back in January! Let’s see what’s next for the Spaniard.
“From what I’m told, negotiations are ongoing between Manchester United and Aaron Wan-Bissaka over a new contract. Nothing done yet, it has to be said, but talks are ongoing between the two parties.
“Wan-Bissaka is open to staying in Manchester but the conditions have to be right for him as it’s an important potential contract for his career. So talks are ongoing and it will continue over the next weeks.”
