Top 10 signings ever made by Jose Mourinho

#2 Thiago Motta/Diego Milito (£9.18m/£22.5m from Genoa)

One of the best double transfers of all time

Yes, this is somewhat cheating, putting two players at the same position, but the simultaneous impact of these two players in addition to the fact that they even joined Inter Milan from the same team verify this decision.

Thiago Motta has a similar build to Matic, however it's his aggressiveness and leadership that stand out the most. Diego Milito, on the other hand, was one of the most relentless goalscorers on the planet from 2008 until 2010.

Motta and Milito really provided Inter with the spark they needed to create something as special as their 2009/10 season. With Motta running the midfield and Milito pretty much scoring every chance he got, Inter simply couldn't fail.

That Jose Mourinho dug these two out from mid-table side Genoa in 2009 may be his most underrated piece of transfer business ever. If Mourinho's critics blame him for trying to buy success, this is probably the best example of how significant the impact of two players can be.
