Did Man United really made a good move for keeping Harry Maguire? I personally do not think he's that great of a centre-back and he will probably become their weakest link for next season but we shall see. I can see the Spurs as more of a threat to City and Liverpool's title run than MU.
They kept Maguire maybe but they have already found an alternative for him at the same time. They have signed Lisandro Martinez for the starting eleven by spending 57 million euros. This is still great for them because they won't have to continue with Maguire in their lineup.
They need a midfielder now and their attempts for Frenkie de Jong still haven't concluded in any way. I hope that they can complete a midfielder transfer soon too to get prepared well for next season.
