#1 Gareth Bale

The 29-year-old Welsh international joined the La Liga giants in 2013 from Tottenham and has since then won a lot of titles with them. Though he has not been consistent, Gareth Bale has delivered the goods when it really mattered on a number of occasions.
He has transitioned well and has grown into a top player over the years, and was able to attract the interest of many big clubs on the continent. Despite that, he played second-fiddle to Cristiano Ronaldo for a long time before the Portuguese left for Juventus last summer.
Despite the departure of the Portugal international in the summer transfer window, the attacker failed to leave his mark this term. In recent weeks, he faced a lot of boos during games and this did not go down well with him and his agent.
There have been claims that English giants Manchester United and his former club Tottenham have been keen on having him. If that is the case, he may leave Madrid now despite the return of Zidane.
