And that will see him become the world's most expensive defender, topping the £75m Liverpool forked out on Virgil van Dijk, 28, in 2018.

The Foxes have already found a replacement for their leader with Lewis Dunk, 27, set to join from Brighton in a £45m swoop.

United have beaten their bitter rivals Manchester City to the centre-back's signature.

Both the Premier League champions and the Red Devils have seen their £70m bids rejected by Leicester.

But after Old Trafford chiefs upped their offer, Leicester eventually sanctioned the deal.

That comes just a few days after Maguire angrily accused Leicester of pricing him out of his mega move.

Jose Mourinho had been desperate to sign the centre-back last summer after the former Hull man's performances for England at the World Cup.

Leicester landed the Sheffield man for £17m in 2017 and will make a healthy £43m profit straight away.

He became a father back in April after wife Fern gave birth to a daughter, nine months after England's exploits at the World Cup.

United are still chasing Sporting Lisbon's Bruno Fernandes and Newcastle starlet Sean Longstaff.

While Romelu Lukaku's future at Old Trafford is still uncertain, with the striker giving a cryptic message to reporters in Australia yesterday.
