Suarez doubled his side's lead before half time and the former Barca man celebrated by cupping a phone to his ear, almost as if reminding Koeman he made a mistake by letting him go.
While the Uruguayan insisted that was not intention behind the celebration, he did take a shot at the Barca boss. “He told me he did not count on me,” said the 34-year-old.
"It was hard, I did not expect it. They were very difficult moments because of the manner [of my departure].
"Koeman called me and told me that I was not in his plans. When Barcelona made it official that they did not count on me, conversations began with Atleti, with Cholo [Simeone], with Miguel Angel.
"There was interest from many clubs, not just Juventus. I wanted to make the right decision, the best for me and my family."
Speaking before the game, Barca president Joan Laporta insisted that club still believe in Koeman, and said: "No matter the result, Koeman will stay on as coach. He deserves a margin of confidence. Koeman is a cule and a reference point for Barcelona.
“I have spoken with him and I have drawn my conclusions. I really appreciate that he is leading Barca at a time of difficulty.”
