Tottenham have a deadline to close a deal for Timo Werner.
The striker is on-loan at Spurs from RB Leipzig to the end of the season.
The Telegraph reports that Werner can be bought for £14.5m courtesy of a permanent option in the deal.
However, Spurs must trigger Werner's purchase clause before June 14, as other clubs will be clear to buy the striker after that date.
Werner, 28, moved on a loan deal in January and has since scored two goals and made two assists in nine games.
