Cesc Fabregas has admitted he's become disillusioned with life as a Barcelona substitute - and has opened the door to an Arsenal return.
The former-Gunners captain left the Emirates Stadium in 2011, joining his boyhood club in a £30m deal.
But despite a strong start to life back in Spain, the 25-year-old has since had to make do with sporadic appearances, often from the substitutes bench.
A crowded Barca midfield including Xavi, Andres Iniesta, Sergio Busquets and new signing Alex Song has made it difficult for Fabregas to cement a starting place, and the Spain international is yet to complete 90 minutes for Tito Vilanova's side this season.
Speaking to Spanish newspaper Marca and quoted on talkSPORT, Fabregas said: "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 teammates 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 teammates or manager see it."
Arsenal retain first-option on the midfielder, and reportedly can resign the Spaniard for the same price as Barca paid last summer.
And despite insisting that he wants to fight for his place at the Nou Camp, a return to Arsenal would surely be Fabregas's first choice should Barca decide to sell.
The former-Arsenal star reaffirmed his desire to stick it out in La Liga, but admitted he would be willing to go if the coach could no longer find a role for him.
"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," said the 25-year-old.
"I am delighted to be a part of this team, but when a coach tells me I have to go I will go - but I will not make it easy for him to do so, by any means.
"I came here to see out my career."
In his first 12 months in Catalonia, Fabregas has won the Copa Del Rey and FIFA Club World Cup, but like Cristiano Ronaldo at Real Madrid, has recently revealed his unhappiness.
But with the transfer window now shut, any sensational move back to the Premier League would have to be put on hold until January.
