Koscielny and Mertesacker combined scored as many goals as Ozil last season.
Sanchez and Giroud were our top scorers last season, which is expected as they are our 2 forwards.
Ozil as our 3rd forward hamstrings our attack by not offering a goal threat, and that only places greater pressure on Giroud and Sanchez to deliver.
Without Sanchez we were limp against West Ham.
Sanchez and Giroud both delivered against Palace.
Sanchez and Giroud both had great chances last night, but Ozil has to carry some of the flak. He offered no penetration.
Ramsey and Cazorla are the support goalscorers from midfield and they both scored 9 and 7 goals respectively last season, more than Ozil, and the team shouldn't rely on them except as a last resort.
The clear missing link in the goalscoring chain is Ozil.
