Manchester United have outbid Chelsea for Monaco midfielder Tiemoue Bakayoko.
The Old Trafford side have offered more than €40million (£35.3m) for the France international and now lead the chase for Bakayoko, who impressed during the principality club's Champions League campaign.
Chelsea had hoped to push through a deal for Bakayoko before the end of the week despite revelations of knee surgery which may rule him out of the start of the season.
Bakayoko, who posted a photo of himself next to a jet on Monday, underwent routine keyhole surgery last month to clean out a knee which had been causing him pain since February.
