Cesc Fabregas has vented his frustration at what he deems to be a lack of first-team opportunities at Barcelona.
The Spain international, who re-signed at the Camp Nou from Arsenal in 2011 for ┬ú30 million, has conceded he is not content with a bit-part role for the club.
He told Radio Marca: “There’s no such thing as a great substitute in the world of football.
“I couldn’t tell you what makes a great substitute. I always wish my team-mates well and put a happy face on.
“If I have to take my unhappy face home then so be it, but I would never let my team-mates or manager see it.”
Fabregas competes for a starting berth in the centre of the park with Andres Iniesta, Xavi, Sergio Busquets and new recruit Alex Song, his former Gunners team-mate.
“Everybody likes to play every minute of the season,” he added. “I’ve always said that I play for the best team in the world, but I came here to compete, to learn and enjoy, not to sit wracking my brains.
“The manager knows what I can offer. But across the three positions that I can play, I am competing with the three best players in the world.
“I’m delighted to be a part of this team but when a coach tells me I have to go, I’ll go.
“But I will not make it easy for him to do so, by any means. I will keep going, looking forward to the time that things change. I came here to see out my career.”
