Real Madrid are prepared to battle Arsenal, Barcelona and Bayern Munich to secure the signing of Red Bull Leipzig defender Dayot Upamecano this summer.
Reports in Spanish outlet AS suggest Los Blancos have become the latest club to consider activating the £55million release clause in Upecano's contract.
However, the Frenchman is prepared to hand in a transfer request to force a move through if bidding clubs fail to match Leipzig's valuation.
The 21-year-old centre-back has helped keep nine clean sheets in 29 appearances this season, attracting interest from Europe's top clubs.
