Barcelona forward, Luis Suarez, has said he won't celebrate if he scores at Anfield against Liverpool in Tuesday's Champions League semi-final second leg.
The Catalans go into the game with a 3-0 advantage, courtesy of a Suarez strike and Messi's brace from the first leg at the Camp Nou.
Suarez, who left Liverpool in 2014 after three-and-a-half seasons, was criticized by some Liverpool fans for celebrating his opener for Barcelona last week Wednesday.
The Barcelona No.9 has since apologised for celebrating, while also noting that he "respects" Liverpool fans.
"I think people know the work I did here," the 32-year-old said.
"I think there will be more applause than whistles. There may be quite a few who are not happy but I think there will be more who are happy and grateful."
"Celebrating the goal last week, people who know about football, who love this sport, know about the importance of this.
"I have all the respect in the world for the Liverpool fans. Because I scored and celebrated with my fans, I say sorry.
"Obviously, it is clear that if I score a goal against Liverpool I won't celebrate it in the same way."
The Uruguay striker, who played 133 games for the Reds and scored 82 goals, added: "Being captain of Liverpool was one of the proudest moments of my career. It is something I won't forget. Playing in the elite with Barcelona was because of Liverpool and what they made me."
