Luis Suarez, who is now an Atletico Madrid striker, has promised not to celebrate if he scores against Barcelona.
Suarez left the Nou Camp for Wanda Metropolitano this summer after six years.
The 33-year-old was informed by Barca that he was surplus to requirements and was forced to leave.
Suarez nearly signed for Juventus, before eventually joining Atletico in a €6million transfer.
The Uruguay striker will face Barca on November 22 and when asked if he would celebrate a goal if he scored, Suarez told ESPN: “If I scored against Barcelona, I would not yell or go crazy, but I surely would point somewhere.”
Suarez has already scored twice in three appearances for Diego Simeone’s men.
