Arsenal manager Mikel Arteta will be looking to avoid another touchline tussle with his counterpart at Liverpool, Jurgen Klopp.
Arteta and Klopp were involved in a clash the last time they played each other at Anfield.
Arteta was furious at a Sadio Mane challenge on Takehiro Tomiyasu, as he felt the ex-Reds winger had elbowed his player on that occasion.
Asked how he would react differently, Arteta said during a press conference: I don't know. I would have to be in the situation again.
I reacted to defend our players the best possible way - but I don't like seeing myself like this, so hopefully not.
That's football. It happens in football and after that we hugged each other and moved on.
The last time we were together nothing happened. I have full respect and admiration for what they've done. We've moved on."
