Tanguy Ndombele is expected to have a medical on Tuesday ahead of his club record move to Tottenham.
Spurs have agreed a deal worth an initial £56.5m with Lyon for France midfielder Ndombele.
The future fee could rise to around £65m due to the add-ons included in the package.
The 22 year-old has also already agreed personal terms on a five-year contract.
And Sportsmail understands he has now arrived in London ready to put the finishing touches to his move.
The fee for Ndombele tops the £42m Spurs splashed out for centre-back Davinson Sanchez in 2017.
He has been a long-term target for manager Mauricio Pochettino and having been keen to sign him in the previous two windows the Spurs boss made signing him his No 1 priority this summer.
Capturing Ndombele would represent a significant statement of intent from the north Londoners and be part of an eye-catching return to the transfer market after two windows without spending.
Spurs are also finalising winger Jack Clarke's £11.5m move from Leeds.
Pochettino said last week about Spurs's failure to spend since Lucas Moura's arrival on deadline day in January 2018: 'It is imperative that this year we strengthen the team.
'We saved a lot of money in almost two years without signing and that should allow us to strengthen ourselves well.'
