I spoke yesterday about the importance of having dynamic grit in midfield and we're going to need that in spades when we visit Stamford Bridge on Sunday.
The home side can be brilliant or woeful and the toxic atmosphere due to the sacking of nice guy Roberto Di Matteo and the appointment of Rafa Benitez in his place can only work to our advantage.
The thing is, Ch*vski have superb players. Torres took us apart earlier in the season and Demba Ba was tricky for Newcastle recently; we struggle to get near to Juan Mata and with Oscar and Ramires equally tricky and evasive, we will have to be on our toes.
The defence can be steadfast - that's why they won the Champions League last season.
But Wednesday's FA Cup win has given me real optimism that we can win.
We need to carry on the good habits we started, chasing down the opposition when in possession and retaining our shape at all times.
If I was an opposition manager I would target Jack Wilshere. He beats players which creates space.
So let them put two men on him, which take away some of their offensive value and will mean more space for Santi Cazorla.
As long as Abou Diaby and Francis Coquelin (who I fear will be dropped) put in the same sort of shift they did in the FA Cup, we should be fine.
While the players have to take credit for putting in a shift worthy of the Arsenal shirt for the first time in a long time, what I don't want to see is the manager bringing back players erroneously as he has had a tendency to do.
He dropped Per Mertesacker for the home fixture earlier in the season and it cost us and while it may seem wise to play two nimble centre-backs against Torres or Ba, actually Mertesacker's positional sense would work to our advantage.
Which brings me to Lukas Podolski. I know he has played a majority of his Germany games wide left and that he was signed with that flexibility.
But his lack of positional awareness and cover is part of the reason why sides target our left and put Kieran Gibbs under pressure.
For me, he's a useful option in that position if no one else is available but he should really be vying with Olivier Giroud for the striker's role just ahead of Jack.
At the moment, the Frenchman is doing little wrong in my opinion and deserves a run of games to add goals to his already impressive build-up play (that flick that left the ball sitting up perfectly for Jack on Wednesday was sublime).
My neighbour at Arsenal made the very valid point that Podolski neither has tricks, outstanding pace or the engine (90 minutes anyone??) to cope as a wide player in England.
That doesn't mean he cannot play a significant role at the club, just not wide left.
If the same side that started on Wednesday starts on Sunday, I'll be delighted.
Unless we sign Cavani, in which case I give Wenger permission to make a change.
Joking.
