Barcelona have hit out at Manchester City in accusing them of unsettling their players after they were linked with a move for Sergio Busquets.
Reports have suggested City are lining up a big-money move for Spain international Busquets as they look to bolster their midfield options.
Barcelona president Sandro Rosell has blasted City and warned them off making a move for Busquets.
Rosell also aimed a swipe at Arsenal for their raids on the club's academy, accusing the capital outfit of luring away their best young players with money.
"Manchester City want to remove our players and want to destabilise us," said Rosell. "It also happens with Arsenal, who come knocking for youth football players and offer them a lot of money.
"Now City have joined in. We are the enemy to beat.
"There are a lot of people who don't want us to win.
"But we must be calm - Busquets is another example like Messi, Valdes, Xavi, Puyol and the rest.
"We have great players and they are 100 per cent Barcelona."
