Yaya Toure would be open to a return to Barcelona, according to the Manchester City midfielder’s agent.
The Ivory Coast international spent three years at Camp Nou before moving to the Premier League champions in 2010.
But following the revelation that the club forgot the 31-year-old’s birthday on May 13, the player’s representative has claimed that Yaya feels ‘disrespected’.
"Yaya is so upset he's thinking of leaving City,”Dimitry Selek told The Sun.
“There are a number of things that have happened that have left Yaya feeling bitterly upset. He must concentrate on the World Cup now. But City have treated him with disrespect and have really hurt him.
“They don't know that money can't buy relationships – no Sheikh can buy a relationship. This isn't about money or a new contract – it's about human relationships and City have shown they don't respect him.
“I repeat – this is not about money. In fact, he would take less to return to Barcelona.
“What happened at his birthday meant the club don't care about him. It was proof. They can say whatever they want, 'Oh we like him but we forgot'.
"Forgot? About Yaya? The player who helped you to be two-times Premier League champions? The guy who helped you win the FA Cup and the League Cup?
"His birthday can be on a normal day and, in a normal team, his team-mates and club would at least give him good wishes.
"But when you win the title on May 11, a day later you go to Abu Dhabi and on May 13 you have a big party to celebrate the title and nobody comes to Yaya to say, 'Happy birthday', what more do you want?"
It’s unlikely that Manuel Pellegrini’s side will take these threats seriously however, as Selek has said the same thing for the past two seasons in order to increase Toure’s wages.
