Manchester United are making serious moves in the transfer market as they prepare for a midfield overhaul this summer. According to Sky Sports journalist Lyall Thomas, the Red Devils are "stepping up their interest" in two standout talents: Atalanta's Ederson and West Ham's Mateus Fernandes.

This surge in activity comes as Casemiro's time at Old Trafford appears to be winding down. The Brazilian veteran is expected to depart next month, with his final home game set for this Sunday against Nottingham Forest—a moment that marks the end of an era for United's midfield.

First up is Ederson, the 26-year-old Brazilian international who has been turning heads in Serie A. Interestingly, he had already agreed personal terms with Atletico Madrid back in March, but that deal hit a snag when the Spanish club balked at his £39 million price tag. Atletico have since shifted their focus to Wolves' Joao Gomes, which has opened the door for United to reignite their pursuit of Ederson. With his contract at Atalanta expiring next summer, the timing could be perfect for a move.

But Ederson isn't the only name on United's radar. The club has also set its sights on West Ham's midfield maestro, Mateus Fernandes. The 21-year-old Portuguese star is reportedly "open" to a switch to Old Trafford, and who could blame him? The chance to play Champions League football is a powerful lure.

Fernandes' situation is particularly intriguing. He's facing the prospect of a second consecutive relegation from the Premier League—having gone down with Southampton last season before joining West Ham. The Hammers have just two games left to secure their top-flight status, and they'll be hoping for favors from Chelsea and Everton in their matches against Tottenham.

Should United make a formal approach in the coming weeks, Fernandes would have the opportunity to showcase his talents on Europe's biggest stage. However, if West Ham manage to stay up, they'll likely demand a hefty fee for a player they've only had for eight months. Either way, this is a developing story that could reshape United's midfield for years to come.
