The Gunners were 4-0 down inside 19 minutes against a rampant Liverpool and eventually went down 5-1, their second heavy defeat of the season after a 6-3 Premier League thrashing at the hands of Manchester City in December.
But they responded to that defeat by taking 20 points from the next 24 available and Arteta says that is Arsenal's new challenge, which starts with a clash at home to a reeling Manchester United on Wednesday.
The Spaniard said: "We know we need to improve and face those games in a different manner because after 19 minutes we were 4-0 down and it was like a car crash.
"The manager was really upset at half-time, that's normal because it wasn't good enough for this football club. It was the angriest I have seen him."
But Arteta says there is no point looking back at a result the players can do nothing to change and he feels they have what it takes to bounce back, as they have already proven this season.
"We have had two big crises already," the Spaniard added.
"I think the Manchester United defeat was a different game to this, but City and this one are really hard to take. We have to react because there is nothing we can do about this now."
Jay D. I hope your right but Chelsea ain't gonna stumble like that too much. Jackio by my count Arsenal haven't won a big game against an in form close competitor since '04. A declining Milan or a dead rubber against Munich don't count. Tott doesn't count. In transition Chelsea doesn't count. The early season win at Pool was huge but at the time big win v. Close competitors? For 3rd and 4th place yes. Need to beat Utd to get '04/05 Rooney dive off our backs but not really a big game v. Close competition tomorrow.- masmaz
