"A club like Barca should show a bit more respect to the intimacy of a club like Arsenal that never make a lot of noise (over transfers) and who always try to do things properly," the former Barcelona trainee said.
"In the last few weeks it's come out that Barca are in for at least seven Arsenal players and there's no need for that.
"These things cause doubts in the mind of the players and unsettle us.
"Arsenal do things differently, always in secret, and that's much more normal.
"They shouldn't do things so that everybody knows about it. If the player wants to go he'll go anyway."
