Seydou Keita has leapt to Lionel Messi's defence after the forward was criticised for an uninspired performance in Barcelona's goalless draw with Valencia at the weekend.

The Argentine endured a tough few days with his national team and has now suffered the same treatment at the hands of the media back in Europe after failing to shine at the Mestalla.

After earning low marks in the matchday ratings from Catalan papers Sport and El Mundo Deportivo, questions were asked about Messi's ability to play in so many matches.

Keita was unhappy that only one Barca player was highlighted for such treatment and feels that the media and fans cannot place such pressure on the No.10.

"He's human, it is normal that sometimes he is not so good," he told reporters after training on Sunday.

"'Leo' is certainly one of our most important players."
