Rafael Nadal has covered an important role in Andy Murray's career. During his teenage years, the British player spent a few days in Barcelona and it was there that he met the Spaniard for the first time, being impressed by his fighting spirit and great passion for tennis.

'I have always been obsessed with competition. I remember deciding I needed to move abroad to a professional tennis camp when I was practicing next to Rafa Nadal and saw him warming up with Carlos Moya!', Murray recalled.

That's why at 15 years of age Andy moved to Spain to train at Emilio Sanchez Vicario academy. Sanchez himself revealed what Murray told his mother when he got back home at 15 age: 'Rafa's out in the sun all day.

He hardly goes to school and he's playing four-and-a-half hours a day. I’m playing for four-and-a-half hours a week. It's not enough.' ALSO READ: Rafael Nadal: 'In ten years from now, tennis could be in danger'
