Manchester United have rejected offers for Marcos Rojo throughout the summer transfer window with Jose Mourinho keen to retain the Argentina international.

Rojo, 26, has remained on the fringes of the United squad this season, failing to make a single appearance in the club's opening three games of the Premier League. Luke Shaw's instant return to form has seen him reclaim the left-back slot while Eric Bailly and Daley Blind have formed an impressive partnership at centre-half, with Rojo among a clutch of players left watching on from the sidelines as a result.

According to the Mirror, Spanish side Valencia have enquired into the Argentine's availability, identifying him as a possible replacement for Shkodran Mustafi following his move to Arsenal.

Rojo's agent Carlos Gonçalves has since confirmed offers for his client, but insists no move is likely to take place before Wednesday's transfer deadline.

"Manchester United rejected several offers from England and from abroad to sell the player," Goncalves told Sport Witness. "Manchester United want him to stay."

Mourinho has named the same back four in each of his opening three league games. Antonio Valencia has emerged as the club's first-choice right-back, leaving Italy international Matteo Darmain consigned to the bench.

Chris Smalling, who played more minutes than any other outfield player for the club last season, has also settled for a spot on the bench since returning to fitness with Bailly and Blind keeping him out of the side, with Phil Jones also out of favour. Stoke City have made enquiries into Jones' availability while Arsenal also reportedly considered a move, but, like Rojo, Mourinho is keen to retain him this season.
