Again, folks say this but the facts don't back it up.
Our defense gives up fewer chances than anyone other than the Rags. We are on par or better in every defensive category except for saves per goal scored.
However on offense we creates as much as all the others in the top 6 but convert at a lower rate than all but 1.
Defense is not the problem. Sure its the position that has the most players fans don't like or think are dispensible. You have Ota, Kola, Clichy, Sagna, Zab and Kompany. All 6 with legimate claims for why folks want them out. But they have not underperformed relative to the other teams in the top 6. The Goalkeepers though, have.
So if we are being honest and following the stats, improving saves to goals ratio, and figuring out what to do to improve conversion of chances are the 2 biggest problems this season. The 3rd being hustle. As our 3rd weakest stat is percentage of duels won.We are at about 43% while all the others are at 50% or slightly above.
So if we really care about solving actual problems
Simply put if our goalkeeper had made saves at an average of the other 5 we'll be 2 or 3 points behind Chelsea. But if our conversion was on average similar to the others, we will be 5 points clear.
Make of that what you want.
