The 34-year-old confirmed in January that he would leave Old Trafford when his 350,000-a-week pounds contract expires, and the club have no intention of offering a new deal. That stance remains unchanged even after a string of influential performances under interim head coach Michael Carrick.

Casemiro underlined his importance again in Sunday's 3-1 win over Aston Villa, opening the scoring with his seventh goal of the season-six of them headers. His display helped maintain United's push for Champions League qualification, with the club now firmly in control of a top-five spot.

The reaction inside Old Trafford told its own story. After celebrating in front of the Stretford End, Casemiro was met with chants of "one more year," a message that continued long after the final whistle. Teammates, including captain Bruno Fernandes, have also voiced their desire for him to remain.

Yet behind the scenes, the direction is clear. Co-owner Jim Ratcliffe has prioritised reducing costs and lowering the squad's average age, with Casemiro's 18.2 million pounds annual salary a key factor in the decision. United opted not to trigger an extension clause or explore a reduced contract, choosing instead to press ahead with a long-term rebuild.

Carrick acknowledged both the player's impact and the finality of the situation. "When something is decided it makes it a little bit easier and everyone understands the situation," he said. "The impact he's had has been terrific - with big moments and goals. That connection with the supporters at the end was a nice moment."

Since Carrick took charge in January, Casemiro has been central to United's resurgence, starting every match and forming a strong midfield partnership with Kobbie Mainoo. He has scored three league goals in nine games during that period, helping the team collect 22 points from a possible 27.

United's improved form has put them six points clear of Chelsea in the race for Champions League qualification, with a return to Europe's top competition within reach after their last appearance ended at the group stage in 2023.

Carrick stressed that difficult decisions are part of football's cycle. "This is no disrespect to Case. He's been fantastic and important in the dressing room," he said. "But as a club, players come and go."

For now, the club's position is unwavering. Even as Casemiro continues to deliver on the pitch - and fans continue to call for a rethink-his Old Trafford farewell appears set to go ahead as planned.
