​Transfer expert, especially when it comes to matter relating ​Manchester United, Duncan Castles has sensationally claimed that clubs all over Europe are laughing at the Red Devils for the fee they are reported to agree for Harry Maguire.

According to multiple reports, ​United have agreed to pay £80m for the Leicester City defender which would make the 26-year-old the most expensive defender of all time.

Castles claims that he has spoken to people at clubs in Europe who cannot believe how much United are going to spend for Maguire. He also adds that clubs similar to United's stature would never pay such an amount for the English defender.

“I’ve talked to various people who are in charge of recruitment at European clubs who laugh at the transfer fee involved in this deal,” Castles said on The Transfer Window podcast.

He continued, "£60m guaranteed, £80m in total, relatively easy achieved bonuses I understand. The suggestion is there is no way a club of similar stature in Europe would buy Maguire for anything like that kind of money."

Revealing what he thinks of Maguire as a player, Castles claimed, "And he (Maguire) probably wouldn’t make it into the national teams of a lot of the top nations around Europe. I guess what those experts think and what we think about Maguire and whether it’s a clever switch or not is irrelevant. In a sense we will find out."

Castles concluded, "He’s going to be put into a Manchester United defence that will be fortified by [Aaron] Wan-Bissaka who is very good defensively and we’ll see how big a difference that makes to the way they play.”

Maguire has made 76 appearances in his two seasons at Leicester, scoring five goals.
