Rasmus Hojlund is being targeted by Manchester United as an attacker to consolidate that offencive line. Otherwise in the defence line, they added Jonny Evans but his contract is short, it is like a test period, to replace Harry Maguire once for all maybe? Manchester United are determined to be more competitive and Ten Hag is trying his best to pick the best selection and have enough substitutes to guarantee the success of the team as it used to be in the past.
Well, about the fact that once and for all to replace Maguire, who is 30 years old, with a player who is 35 years old, sounds quite surreal for me personally, although I do not deny that for one or two seasons you can talk completely, but about forever ... 
Although, in principle, I believe that Maguire has not yet said his last word as a player, but it really bothers him that expectations from him are much too high, given the salary and money that was paid for his transfer at the time. Hojlund's transfer could benefit the club and looks like quite an asymmetric response from Manchester United to Haaland's presence at Manchester City.
