Well goals I ignored because if you are expecting Ozil to be scoring anywhere near the same amount of goals as Sanchez I think you are confused over what kind of player he is. Especially so considering you agreed with me some time ago that Sanchez was a good option to play up front.

Be interested to make the comparison between them over chances created

But fair enough if you want to want to make Ozil the focal point for criticism due to a lack of assists in the last nine games than up to you. I think his assist rate would be off the chart with a decent striker in front of him. I think criticism of him largely indicate attributes that are not part of his game, not every chance needs to be gilt edged if you have a striker mopping them up (although Giroud and Welbeck often miss gilt edged chances as well).
Our chances to goal ratio is probably one of the lowest in the league. I personally might have rested Ozil for a few games that we should be winning anyway (though of course Wenger has redefined should win games to should win but probably won't).

As for goals I am intensely relaxed by that side of his game, scored eight this season and if other players were doing their bit it wouldn't be an issue. But that goal tally is about par for Ozil, I don't think he got into double figures for Real Madrid just provided loads of goals for Ronaldo and Benzema.

Anyway we aren't going to agree on this, I just think by a country mile Ozil is the most gifted footballer in the team and therefore when someone says they wouldn't be that fussed if he went seems to confuse me greatly.
