Real Madrid boss Zinedine Zidane has claimed that his team were "lacking physically" as they lost 3-1 to French champions Paris Saint-Germain in the International Champions Cup on Wednesday night.

Zidane was not happy that his side suffered defeat in their first pre-season match, but the Frenchman is confident that Los Blancos will "pick up the pace" as the new campaign approaches.

"There were some good things about the game, but we're lacking physically. We only started 10 days ago. I'm happy with the work, but not the defeat, of course. We can never lose. Even a friendly. This is Madrid. But we'll pick up the pace and then La Liga is very long and we have to start well," Zidane told reporters.

"Maybe we lacked a little aggression for a strong rival. Especially in the first half. We had the ball and we had chances. Tactically we have to work more and find the automatic moves. We'll do it little by little."

Cristiano Ronaldo, Gareth Bale, Sergio Ramos, Pepe, Luka Modric and Toni Kroos were all missing for the Champions League holders in Ohio.
