Former Barcelona defender Dani Alves has admitted that he found it 'difficult' to mark Cristiano Ronaldo when the Portuguese star was playing for Real Madrid.
The pair played against each other multiple times in El Clasico while they were playing in LaLiga with varying success against each other.
Ronaldo used to play on the wing and would directly come up against Alves, who was the Barcelona right-back for and incredibly successful eight years.
At the time the rivalry with Madrid was very intense, and Alves has described Los Blancos star Ronaldo as one of the hardest opponents he has faced in his career.
