Luis Gustavo made an interesting Cristiano Ronaldo admission

Al Ittihad v Al Nassr - Saudi Super Cup

Former Bayern Munich midfielder Luiz Gustavo, who currently plays for Saudi Arabian side Al-Nassr, made an interesting admission about Cristiano Ronaldo.

Gustavo claimed that the five-time Ballon d'Or winner's presence makes matches more difficult for Rudi Garcia's team as opponents want to give their best against the legendary player.

The Brazilian midfielder said after his team's win against Al Fateh (via RT Arabic):

“Certainly, the presence of Ronaldo makes matches more difficult for us as all teams seek to participate against him in the best possible way, and he gives motivation to everyone. His presence at Al-Nassr gives a great advantage to the group because we learn from him every day, given the great capabilities he possesses, both technically and physically.”

Ronaldo and Co. will return to action on February 9 as Garcia's side take on Al Wehda in an SPL clash.
