Robben joined Real last August for a fee believed to be more than £20million, but a series of injuries have severely limited the impact the Holland international has made in Spain.

The 23-year-old winger, who also struggled with fitness problems at Chelsea, has started only five matches for Real.

But Mijatovic said: "He is only 23 and he has a lot of quality. This is not something that doesn't have a solution - we need him to relax a little, because it has not been easy mentally for him.

"It is too soon to say that we have made a mistake. We need more time. Robben will be very useful."
