Tottenham Hotspur, Manchester United, Manchester City and Paris Saint-Germain reportedly want Juventus winger Douglas Costa.
The Brazilian is widely expected to move on at the end of the season, as his form has been poor, he suffered injury problems and was involved in a car crash.
He also had disciplinary issues, with a four-match Serie A ban for spitting at an opponent.
Interest from PSG and both Manchester clubs was already known, but now Tuttosport claim Tottenham have joined the race too.
Juve paid €46m plus bonuses to get him from Bayern Munich in 2017, but Douglas Costa scored only one goal in 24 competitive appearances this season.
The Bianconeri want at least €50m to sell the 28-year-old Brazil international.
