Mason Mount will become Man United's first signing in the summer transfer window of 2023.
So, who wins and who loses when the English star arrives at Old Trafford?
Having played 70 matches for the club and national team last season, Fernandes can now rest assured with Mount around. His creative abilities also relieve the pressure on Fernandes, making the Red Devils even more unpredictable.
Mount will primarily play alongside Fernandes, but he can also fill the position of the former Sporting Lisbon midfielder. When both are in top form, Fernandes becomes a formidable force.
Casemiro will benefit from having a young and energetic player like Mount partnering with him in central midfield. Instead of pairing with the 31-year-old Christian Eriksen, the Brazilian international will pair up with the 24-year-old Mount.
Ten Hag identified Mount as a priority target, and Man United quickly helped him complete the deal. The Dutch manager is one step closer to implementing his high-energy pressing football, with Mount considered a key element to take the Red Devils to the next level.
Man United's technical director failed to secure his priority target, Frenkie de Jong, last year. This time, he successfully completed the task.
If Mount wasn't acquired this summer, Murtough's capabilities would have been questioned. Fortunately, the successful signing of Mount only cost Old Trafford £55 million plus £5 million in add-ons.
There's no denying that losing Mount is a disappointment for Chelsea. The midfielder, an academy graduate whom The Blues wanted to keep, slipped away. Chelsea also won't be pleased to receive just £5 million in add-ons from this deal, as they might regret seeing Mount lift trophies with Man United.
Mount's departure is a result of a disappointing year for Chelsea, finishing 12th in the Premier League and missing out on Champions League qualification.
Fred is likely to be sold due to Mount's arrival. The 30-year-old Brazilian midfielder only started 12 Premier League matches last season, and staying at Old Trafford would further limit his playing time. The same goes for McTominay.
Christian Eriksen will lose his starting position at Man United with Mount's arrival. In a way, with the addition of the former Chelsea star, Eriksen will have more resting time. He may benefit from avoiding overexertion. It was evident last season that Eriksen struggled upon his return from injury and lacked energy.
