Mourinho hit at out the Gunners following Tottenham's 3-1 defeat at Bramall Lane after taunts from the club's media team.
"It's going to be a weird one, it's going to be the first one where it's going to be in this type of situation," he told ESPN. "It's going to be funny to hear Mourinho talk about it.
"I saw the other day he already started to have a go at Arsenal, that was pretty funny at the end of the day.
"But no, listen, I didn't think about it too much. Because I don't think about Tottenham and I never did in fairness so it won't change."
