Manchester United may sign more than four players in the summer window, with a major squad overhaul planned for next season! Many are facing farewell performances.

After Manchester United's 3-1 victory over Aston Villa, West Stand fans chanted "one more year" to Casemiro. Actually, this phrase might suit more than just "Fat Tiger." The futures of manager Carrick, center-back Maguire, and even captain Bruno Fernandes are still unclear.

"The Athletic" advises Manchester United fans to fully enjoy this moment and appreciate the displays of Casemiro, B费, and Carrick. Especially the 34-year-old Casemiro, whom owner Sir Jim Ratcliffe views as a symbol of wasteful spending and excessive star-chasing recruitment policy, but the proud Brazilian has proven with actions that he didn't join United solely for money.

The fans' earnest pleas likely won't change Casemiro's future, and United may deeply miss him later. Since announcing his summer departure, Fat Tiger no longer needs to consider other matters, focusing only on playing well—which not only affects United's current results but also directly impacts the contracts he might secure elsewhere.

Italian transfer expert Fabrizio Romano, The Athletic, and United manager Carrick all indicate Casemiro is almost certain to leave. This will disappoint United fans, but recalling past examples like United legend goalkeeper De Gea and Liverpool striker Salah shows sometimes parting at peak performance is best. Otherwise, if performance declines later, those who clamored for him to stay might become the harshest critics.

Moreover, based on current circumstances, Casemiro might not be the only departure. Behind him stands Maguire, whose contract renewal is also pending. The 33-year-old English defender is a key part of Carrick's squad; his contract expires June 30, and his current performances aim to secure better terms in negotiations with Ratcliffe's INEOS group, such as less salary reduction and a longer contract.

Villa striker Ollie Watkins' form has dipped this season, but he still scored 8 Premier League goals, just one less than United's top scorers Mbemo and Sesko combined, and netted the winner in Thursday's Europa League knockout match against Lille. Maguire successfully neutralized Watkins, ensuring Villa's No.11 had no shots before being substituted after 60 minutes.

Compared to Maguire, B费's likelihood of staying this summer is almost 100%. This differs greatly from last year, when growing opinion suggested selling the Portuguese midfielder quickly, and many found it incomprehensible that the club rejected a €100 million offer from Saudi oil-backed investors.

Now, B费 has provided 16 Premier League assists for United, nearing the historic record of 20 assists in a single season. Fans also advocate he should win Premier League awards, including PFA Players' Player of the Year, FWA Football Writer's Association award, and the official Premier League Player of the Season.

Since the start of the year, no other Premier League player has outperformed B费. Before that, he also performed excellently, despite being unreasonably placed in a midfield role in a 3-4-3 formation. This season, B费 created 98 chances, 40 more than second-placed Arsenal midfielder Declan Rice.

There are two counts for B费's assists at United: exactly 100 or 103. This isn't surprising due to differing assist criteria. Regardless, B费's importance to United is undeniable. Manager Carrick stated post-match: "Bruno is a player we don't want to lose."

Carrick said this because his own future is uncertain, so regarding summer departures and signings, he can only offer suggestions now. The UK's "The Sun" reports United considers signing two midfielders to replace Casemiro, a center-back if Maguire leaves, and possibly a left-back.

Luke肖, 30, is the only United player to start all 30 Premier League matches this season, but his contract expires next year, and doubts exist about his ability to handle next season's denser schedule.

However, signing just four players likely isn't enough. If Altay Bayindir leaves, United will need a new goalkeeper; if Zirkzee is sold, the team will require a forward, possibly a left winger.

The coming months will determine how different next season's United will be from this one. Currently, Red Devils fans can only enjoy this moment and hope the positive trend continues.
