Arsenal boss Arsene Wenger says fans should be happy seeing Everton boss David Moyes clash with Manchester City's Roberto Mancini.
The bosses angrily confronted each other as a compelling Premier League encounter at the City of Manchester Stadium on Wednesday night - which Everton won 2-0 after goals from Tim Cahill and Mikel Arteta - went into stoppage time.
The pair needed to be separated by fourth official Howard Webb after City boss Mancini took exception to Moyes picking up the ball - an action the Italian interpreted as time-wasting.
Wenger insists such flashpoints are understandable when passions run high, with so much at stake.
Wenger said: "I had some [incidents], but we are all under pressure.
"During a game at one specific moment it can happen that, for a fraction of a second, we lose it a little bit.
"It can happen to anybody.
"Even if after the game, 'come on let's behave properly' it can still happen.
"It just shows that we are humans like everybody and that we care."
