Former Chelsea defender Alex insists he has nothing against his former team as they prepare to meet this week in the UEFA Champions League.
Alex, who won the Premier League and two FA Cups at Stamford Bridge, comes up against his former team for the first time since leaving them in January 2012 when Andre Villas-Boas sold him to Paris Saint-Germain.
The Brazilian says he harbours no bad feelings towards the west London club, and the only person he had an issue with was then manager Villas-Boas.
"This is not about revenge. I had problems at the time with one person, who was Andre Villas-Boas, but not with the club," he told reporters ahead of the first leg on Wednesday. "I had a good relationship with everyone over there.
"It is not about revenge but I want to get through this round on our way to winning the Champions League."
Alex did admit that it will be a difficult tie and a tough call between the two teams.
"I don't think there is a big difference between the teams," he said.
"They are a team who are going to come to our stadium to get behind the ball and play on the counter-attack. We have to pay attention to this. For me, it is 50/50."
The former Chelsea player believes that Eden Hazard is the real danger for Chelsea and that his team will have to keep a close eye on him.
"Hazard is a very good player," the 31-year-old added. "We have to be careful down our right flank but also in their midfield. Chelsea are equally dangerous on free-kicks because they have players who are very good at heading."
