Juventus' agreement with Liverpool midfielder Emre Can is not watertight.
Turin's Tuttosport says Juve face stiff competition to lock down Can to a rock solid pre-contract agreement.
While some agents have insisted the agreement is in place, it's emerged that Can is also fielding interest from Premier League rivals Manchester City and Spanish giants Real Madrid.
City boss Pep Guardiola is a big fan of Can and believes he can be a natural replacement for the departing Yaya Toure. Real, meanwhile, are seeking to rejuvenate their squad this summer and see Can's energy as an option in midfield.
With Can a Bosman prospect this June, snapping him up for nothing is attractive to all three big clubs.
