As the January transfer window approaches, this special report delves into the IMScouting database to find the most effective signing from summer 2009.

The report calculates the number of goals and assists in relation to minutes played for each player transferred during summer 2009. 

Many of last summer's big money transfers make the top twenty list, including Cristiano Ronaldo and Karim Benzema from the latest generation of Real Madrid 'Galacticos'.  Not to be outdone, Barcelona's big purchase, Zlatan Ibrahimovic is also shown to be very good value for money.

There are of course some younger prospects who look to be wise investments for the future, such as 23 year-old Radamel Falcao , who joined Porto from River Plate.

However, the report interestingly shows how older, more experienced players make for excellent signings, particularly for clubs who are looking for an immediate impact.  Prominent in the top ten are players such as Inter Milan's 30 year old striker Diego Milito , FC Basel 's Alexander Frei and top of the entire list isAjax's Marko Pantelic.  The 31 year-old striker has scored 8 goals since his move from Hertha Berlin.

The special report can be seen below.  You can see all special reports at theIMScouting special report section.
