I think the first leg at home is better as least we are still in the tie when we play at home.
if we defend against griezman and costa like we defend against most teams think we could be in a spot of bother.
I am actually looking forward to it, I haven't looked forward to a game in a while.
I think the realisation could be that regardless of results Wenger will decide when he goes. So might as well bring home a European trophy, as the best case scenario is win the Europa league for the trophy factor not the CL football factor, Wenger decides now is the time to go as he has finally won a European trophy. A new manager comes in with the promise of CL football. Worst case we get demolished by AM, Wenger stays anyway as he convinces Kroenke that we have progressed by making the semis and we can have another crack at Europa league next year.
