The club’s record goalscorer looked set to leave United this summer – with a return to Everton high on the list of potential suitors.
The 31-year-old forward, who has scored 253 goals for United, has struggled for game time this season under Jose Mourinho.
Rooney only managed 25 Premier League appearances last season and failed to set foot in the Europa League final.
But United have changed their Facebook header picture to include Rooney in next season’s away kit.
Rooney puts on an intimidating pose, with Jessie Lingard, Paul Pogba and Ander Herrera also featuring in the image.
But including Rooney in such an attention grabbing place is surely a hint that he will be staying with Mourinho’s men.
Adidas have based the black kit, which is designed on the iconic 1990-92 away kit and have announced that next year’s kit ’embraces all the hype and amplifies it.’
“It’s no secret that the mighty Red Devils dominate and command respect from their opponents,” read an official Adidas statement.
“Like the giants themselves, the ’90-’92 Man United away kit is celebrated, hated and impossible to ignore. A bold version of the iconic kit, this men’s football jersey embraces all the hype and amplifies it.”
