Rosell's club felt aggrieved by the decision of the Spanish federation's competitions committee not to punish Real Madrid utility man Pepe for appearing to stamp on Barca forward Lionel Messi's hand earlier this month.

Rosell said in quotes reported by marca.com: "I like to assess [referees] at the end of the season but this year it doesn't look good.

"If [the competition committee] does not work well then we will have our say, because football is supposed to be based on fair play."

The European champions travel to Valencia tomorrow night for the first leg of their Copa del Rey semi-final.

They will be without the injured Pedro, Andres Iniesta, Ibrahim Afellay and David Villa for the match at the Mestalla.

Meanwhile, the club confirmed that 20-year-old winger Isaac Cuenca will sign a new contract this afternoon and is set to train with the first team this evening.
