Cristiano Ronaldo is doubtful for Real Madrid’s league opener at Real Sociedad on 21 August as he is still recovering from the knee injury he picked up at Euro 2016.

The 31-year-old forward, who scored 51 goals in 48 games in all competitions for Real last season, is on holiday in the United States and will already miss the European Super Cup final against Sevilla on 9 August.

The Real Madrid coach Zinedine Zidane said he would not rush Ronaldo back into action after he sprained his left knee during Portugal’s 1-0 extra-time win over hosts France in Paris last month and Real have not set a date for his comeback.

“Right now he still has his injury,” Zidane said following Real’s 1-0 win over Bayern Munich on Wednesday in the International Champions Cup in New Jersey.

“Obviously he wants to be back but we need patience and for him to be calm. He will be back with us soon in Madrid.”

Zidane has also been without Gareth Bale, Toni Kroos and Pepe throughout Real’s pre-season with the trio scheduled to join up with the squad on 6 August. All three were granted an extended holiday following their participation at Euro 2016.

Despite not being at full strength, Zidane has been impressed by what he has seen in his team’s preparations so far. “Overall I am delighted with the work we have done this pre-season,” he said. “But we must continue because it’s going to be a long campaign and we have to continue to work in this manner. We need to get better as a team.”

Real, who finished runners-up to Barcelona in La Liga last season, beat Atlético Madrid to lift the Champions League trophy in Zidane’s first season in charge.
