But Pochettino is not listening to the outside noise and suggests Xavi is simply trying to create some uncertainty amongst the North Londoners due to his hatred for Barca's arch rivals Espanyol - a club the Argentine has a strong association with.
"Is Xavi working for Manchester City maybe? He wants to help Guardiola," said Pochettino.
"Because we are doing things and the club has a lot of potential, the focus is on our talented players.
"But my relationship with my chairman Daniel Levy is so close. We have our plan to try to improve. The players that we want to keep, we will keep.
"He said to me, 'We don't need money'. If we sell players it is because we want to sell players. We will sign players we want to sign. All the decisions we take are to improve the team."
