Arsene Wenger revealed he had to tell Liverpool manager Jurgen Klopp to calm down during Arsenal’s 3-3 draw at Anfield on Wednesday.
Liverpool led twice through Roberto Firmino but goals to Aaron Ramsey and Oliver Giroud saw them pegged back twice.
Giroud put Arsenal in front early in the second half but a goal from second-half substitute Joe Allen saw the game end all square.
Klopp was characteristically vocal on the sidelines throughout the six-goal thriller, and Wenger warned him he needed to tone down or face being sent off.
“I told him ‘calm down because they will send you into the stands here’,” said a grinning Wenger.
“At Liverpool, it is very tight – you are very close to each other.
“He had a little problem with the fourth official that he will explain much better than I can because I don’t know why.
“It was all right, there was no bad feelings at all.”
