Lucas Hernandez enjoyed an outstanding World Cup with France to persuade Jose Mourinho he was the right man for Manchester United.
United were ready to trigger the Atletico Madrid defender's release clause £71m (€80m).
And despite penning new terms with Atleti earlier this year, Lucas had a big decision to make after United made an aggressive offer.
The Premier League side were prepared to double the 22-year-old's wages to lure him to Old Trafford - but Lucas said no.
"I'm still at the club of my life," Lucas is quoted as saying by Marca after being tempted to seek a move.
United were left without a defender in the end, to Mourinho's dismay and Diego Simeone's delight.
Now a pivotal part of El Cholo's side, Lucas will be looking to cement his place for both club and country.

Filipe Luis appears to be on the way out for club, though Benjamin Mendy poses a greater threat in the long term for Les Bleus.
Lucas could also move inside to play centre-back for his country, though the partnership of Raphael Varane and Samuel Umtiti appears untouchable.
Stuck in 10th after three games on just four points, five behind Barcelona and Real Madrid, Atletico will be determined to pick up a win after the international break to reaffirm their title credentials.
