For the criticism Giroud gets, he's definitely one of the better 2nd/3rd choice strikers in the PL
He is a very good striker
Very entertaining game with two teams failing to defend and attacking well, won by use of the bench. Wenger brought on Ramsey who began creating havoc and switched formation so Shakespere brought on Amatery which nullified things. We were on top but struggled to break through so Shakespeare take off a midfielder for a striker and suddenly space opened up, Ramsey and Giroud both scoring from bench.
Lot to like going forward for Arsenal, Welbeck and Oxlade caused a lot of trouble down the left, Ramsey created a lot of problems with his late when he came on, we looked dangerous when we crossed the ball in or had central midfielders clipping ball in. Lacazette looked dangerous in the box and did well when moved to left, was times where he seemed surprised by the muscle in the Prem and got knocked off ball a bit too easily. Credit to Wenger for being willing to change the system, it is nice having plans b's!
Our problems were obviously defensive, some due to rust, some due to selection (we could have used Gabriel and Chambers so no need to go for two left-wing backs at heart of defence) and some more concerning. A lot of sloppy passes putting us back under pressure, Bellerin and Ozil were awful at shutting down their flank once we were 1-0 up and Leicester's equalizer came from third dangerous cross, our backline and keeper did not handle the crosses well (Cech improved on that in second half), fell asleep at corners.
