Over recent weeks we have been using a data set of transfers made by Premier League clubs over the last four seasons. From this data, we have been able to give a measure of how good-value a signing has been, which nations have provided the best players, and which players have adapted the best to the Premier League.
Now we will be tying this together by looking at the individual clubs within our data set to see which ones have conducted the best business.
We will look at which clubs have got the best performances from their players, given how much they paid for them. For each club's signings (excluding free and loan deals), we estimate the level they should reach, using our previously-derived formula:
Of the clubs with sufficient transfers within the data set to merit examining, the most notable are Arsenal, whose average of 0.22 is more than double that of the next-highest team. Their signings include Alexis Sanchez, whose performance level of 7.80 was the highest of all players in the data set. Signings such as Özil, Debuchy and Gabriel all also out-performed the level their fees suggested.
You can use the widget below to select a team and see how each of its transfers were rated. Just use the drop-down list which appears when you select the team name at the top.
Arsene Wenger's transfer policy at Arsenal has been the centre of much discussion over the last few seasons. However, we have found that his side appear to be the best-performing side in terms of value for money of any team in the Premier League (barring QPR, who only had three transfers recorded).
Needless to say, each club had its own hits and misses, and the greater spending power of the larger clubs means they can absorb the impact of the misses much easier. Next time we will be looking at how a team's performance in the transfer window affected their position in the league.
