James Grayson tweeted a link today to a piece from June of this year on whether Roberto Di Matteo had in fact fared better than Andre Villas-Boas while at Chelsea, at least as far as total shots ratio (TSR) was concerned. The results were remarkable.

The teams that finished in the the top four spots in the Premier League last year maintained on average a TSR in the .600-.700 range. Di Matteo’s TSR since taking over Chelsea from AVB ahead of the current season hovered around or just below the .500 range, which would be commensurate over an entire season with a mid-table points total.

I plotted Di Matteo’s TSR for the season so far, expecting a higher average based on some impressive results and a score of solid summer purchases in Oscar and Eden Hazard. His season average, excluding league cup results, was .498.

Again, TSR should be taken as an indication of a team’s ability to control the ball, which shows up in the ratios to shots for and shots against. It strongly correlates with final table position. It’s clear that Di Matteo’s new iteration of Chelsea, despite it’s impressive results in the European Cup in particular, was not a dominant side in the long-term. We can deride Roman Abramovich for hiring him, but his less obvious numbers were alarming to say the least.
