Cesc is waiting for Barca and Arsenal to agree a fee so he can return home to the Nou Camp.
Alves went through a similar experience when trying to get his move from Sevilla and has sympathy for his potential new teammate.
Alves said: "A player should not be surprised his club is disappointed that you are going, we must be sensitive.
"I forced my departure from Seville. I thought the train had passed and I could not allow the chance to escape."
On Barca's pursuit of Udinese star Alexis Sanchez, Alves added: "I hope Barca finish his signing as he is a unique player."
