It is still a rumor, we don't know how serious Chelsea to sign Maguire. I even think Chelsea current defenders are better than Maguire. Even if they are not strong enough but they don't score own goals at least. 
I hope this will never come true. I would like to give 1/10 rating for chelsea's management if the club will be recruiting garbage player like him. The worst sign that's gonna be made by chelsea. Meguire can do nothing. He was very useless in manchester united. Chelsea must not be stupid enough to sign him as a new player. Meguire shall go to the aston villa rather than chelsea. The most stupid playern in EPL with so many blunders that being made by him. Meguire gonna be a flop for chelsea if this transfer gonna be real.
Harry Maguire is 30 years old, his market value is €20m. No team will spend €40m for Maguire, it is just nonsense to buy a player who has bad performance and he is no longer young defender. Moreover, €40m is overpriced since he is only valued €20m. I assume any club who is interested to sign him for below €10m.
It's not even a team wanna spend 10 million to buy him. I do agree with you if it's a non sense thing to see him being priced so high like that. He shall be worth 5 millions. MU was so crazy by asking 40 millions. There are great defenders available in the market rather than try to buy him.
This gonna be a very bad story. So many people will be mocking chelsea if this transfer will happen. No more stupid player signed by todd boehly. He's fucking stupid.
