I don't think he is. I think he's looking at Giroud and Podolski and thinking this isn't going to be enough to win anything, and if that is his motivation at this point then it isn't going to make him stay - like most clubs in the league we can't guarantee trophies. The model of the club is largely fine. Perhaps spending a bit more money would be useful, but the issue is more about signing cover when we need it. I'm not saying lets spend 50m, but a couple of decent backup players for midfield/defence wouldn't cost a fortune, and perhaps being unwilling to spend where necessary has cost a couple of gems who we could have signed but were too slow.
Tbh I dont think he ever had any intention of staying. His statement was all about burning bridges at the club, and trying to make it as hard as possible for the club to hold onto him.
