Tanguy Ndombele visited Tottenham's Enfield training ground ahead of a club-record move from Lyon.
Details are still being finalised but Spurs expected to complete a deal which could be worth more than £60million for the France international in the coming days.
Ndombele is expected to put pen to paper on a five-year-deal which will see him become one of the club's highest-paid players, a considerable increase on his current wage, thought to be between £50,000-£60,000-a-week.
The 22-year-old made 49 appearances across all competitions last season, particularly impressing in the Champions League as Lyon took four points off Manchester City in the group stage and held Barcelona to a draw in the last-16 first leg.
Tottenham remain in pole position to sign Fulham's Ryan Sessegnon but much of their business depends on the future of current first-team players, including playmaker Christian Eriksen and right-back Kieran Trippier.
