Barcelona goalkeeper Victor Valdes was delighted for Cristian Tello after victory over Real Sociedad.

Tello struck on his full home debut in the narrow win.

Valdes said: "I want to congratulate him for his first goal with the first team, we have the best youth system in the world.

"It's important to win all the games that we have to play, we are in a situation that leaves us with no margin of error, we have to keep on winning three points each week and wait for Madrid to stumble."
