Top 5 release clauses in football

#3 Isco Alarcon, Marco Asensio - £620m

The duo is an integral part of both club and country

Francisco Román Alarcón Suárez is a name that's almost as big as a £620m buyout clause. However, Isco, as he is commonly known, is making the headlines for his game, week in and week out. In a Galacticos team studded with stars, the lad has proved himself to be one of the best attacking midfielders in the world.

Isco moved to Real Madrid in June 2013 from Malaga but was often deemed small to play in a physical league like the Spanish League. He struggled initially in the 4-4-3 system that manager Ancelotti played at Madrid, he gave a good return of goals and assists whenever he played.

With opportunities coming thick and fast under Zidane, Isco cemented his position in the squad and has become indispensable to the Galacticos now. A contract renewal and an imperious release clause are testaments to how much the club values the player.

Marco Asensio was scouted and signed by Real Madrid as an exciting youth prospect in November 2014. He was loaned to Mallorca and Espanyol to get more game time and made his proper debut for Madrid in the 2016-17 season.

He has become a fan favourite since then and his performances have earned praise from many big names of the sport. He renewed his contract in 2017 and the humongous release clause means Real Madrid mean serious business with their player.
