5 players who can potentially break Neymar's transfer record when they move

#3 - Isco:

Francisco Román Alarcón Suárez, commonly known as Isco, has been one of the most decisive player for Real Madrid in the past 12 months. Despite a hard time in proving his worth under the guidance of Carlo Ancelotti and Rafa Benitez, it seems that the Spain international has finally cemented his place in Zinedine Zidane's starting lineup.

Crucial in the late stages of the Champions League and La Liga, Isco was one of the main reasons in helping Real Madrid overcome Barcelona's dominance and finally claim their first league title since 2013.

With a release clause of over 700 million Euros, no club in the world has the financial power to trigger his buyout fee - besides the fact that the UEFA Financial Fair Play rules would certainly have its say if such an unimaginable fee was to be discussed.

However, if Isco was ever to be sold, then Madrid would certainly ask for an extremely elevated fee that would surpass what PSG had to pay for Neymar.
