Real Sociedad coach Imanol Alguacil says they must be ambitious against Barcelona.

La Real will host Barca tomorrow.

Imanol said: "Barça is always important and tough, the normal thing is to lose, but the games have to be played. It's going to be a great game.

"Barça has respected us a lot for a long time and they come out differently against us.

"They like to have the ball and so do we. But we have known how to come together and come out in transitions when we have not been able to gain possession. There are going to be moments for everything, fatigue accumulates for everyone and we have to know how to manage it.

"To beat them I think you have to be daring, that's why we have conceded goals at times, other times we have been close to winning and last year we won there. We will have to play our best game and make sure they don't have their day."
