Football: Top 15 worst signings of Jose Mourinho (With Pictures)

12. Nuri Sahin 

Those who focus on the bad signings that Mourinho has made while being the boss at Chelsea may have had this one slip from their memories. Nuri Sahin left Borussia Dortmund to join up with Mourinho and Real Madrid before the 2011-12 season. That experiment was ended after Sahin had played in only a handful of matches for Real. Sahin was loaned out to Liverpool, where he was more of a disappointment than he was a star player. Sahin was a bust for Real and for Liverpool, and his time spent with Mourinho at Real is now but a memory.
