I
arrived home this evening to a pleasant series of emails from Manchester City
Football Club, specifically their analytics department. For those
of you who are unaware of this department please take a look at their website. I
too was unaware less than 24 hours ago until reading this post over at A Football
Trader’s Path. Data analysis is what I do for a living (technically it is “Business
Intelligence”) and this is the sort of project which interests me. I don’t have
anywhere near enough spare time to replicate some of the more ambitious
projects out there but I was hoping to do a few interesting visualisations with
the data. Exactly what these
visualisations were I hadn’t really thought about so I was a little taken aback
when I checked my emails.
Lacking
inspiration but wanting to dive right
in, I remembered hearing about Theo Walcott moaning about wanting to be played
as a striker. I decided it might be interesting to delve into his stats last
season. As it turns out it wasn’t, he played every game out on the right wing.
The only other player to play in the same position in the same formation over a
reasonable number of games was Nathan Dyer. Theo scored more and set up more
per game, their crossing accuracy was about the same but Dyer was much more
involved, passing the ball successfully 50% more often. That was about as far
as I got with that one before I realised I’d need to spend a significantly
greater amount of time analysing the data before I got anything meaningful.
Undeterred
I then remembered how much I dislike Scott Parker as a football player and
decided to see just how often he passes backwards. Turns out there was only
more disappointment there. The graph below is a scatter plot of all players who
passed more than 200 times last season and the percentage of those passes which
went forward. I marked out 4 data points. The black square is Scott Parker who
was nowhere near the worst offender in the league with a massive 28.3% of his
passes going forward. No, that prize went to Swansea’s (now of Liverpool) Joe
Allen (red diamond) who sent only 15.4% of his passes in front of him. The
other 2 highlighted points are Luka
Modric (green triangle) who sent 26.9% of his 2656 passes forward and Clint
Hill (yellow diamond) who was the only outfield player to hit over 60% of his passes forward (60.5% of
489). A slightly fairer graph is below the first that shows only midfielders playing in
the most defensive midfield position available.
Not
the most exciting piece of analysis, but after getting excited at the prospect
of writing about how glorious or terrible Theo was I felt like I needed to
write about something. Also I won’t in good faith be able to tell my friend who
supports spur that Parker should go play for Barca because they can’t pass
forward either. I will however be bringing Joe Allen up with my Liverpool supporting
colleagues first thing in the morning. Hopefully over the next few weeks as I
try and turn this flat file into something more usable I’ll be able to come up
with some interesting statistics to share. Until then I’ll leave you with the
news you’ve all been dying to hear, Beacher is now 52-0 against me.
