5 worst signings made by Jose Mourinho

#3 Baba Rahman

Baba Rahman is still on Chelsea's wage books

As we continue on our list and move forward, Chelsea fans must think Jose Mourinho brought a lot of underwhelming players to their club. Well indeed he did and Baba Rahman is part of our list. The Portuguese was in his second spell with the Blues and had signed a four-year contract in August 2015 with the Blues.

If Jose Mourinho had known he would be off to a horror start and leave Chelsea in December that year, he wouldn't have dished out £23 million on Baba Rahman, never. An injury prone player, it was very difficult for the Ghana international to establish momentum with the first team.

He felt a little behind Premier League standards as well, but there wasn't enough fitness to keep him running to match standards. At 26, he should be entering the prime of his career and playing regular football for a European club's first team. At least that's the desire, but he's playing for Chelsea under 23s. Oh Jose Mourinho, look what you did, left him on his own while you went to Manchester United.

In his first season, he made 15 appearances and was able to throw in tackles to protect the defensive line from the leftback position. Managers changed, loan spells occurred but Baba Rahman remained a figure lost in oblivion. Quite remarkably, he is still contracted to Chelsea and has made 10 appearances on loan at Reading this season.

#2 Mateja Kezman

Mateja Kezman arrived with a reputation of a goal scoring machine

One thing is for sure, Mateja Kezman loved his time at Chelsea. He was quoted as saying: "But the transfer to Chelsea made my dreams come true. That was the best thing that ever happened to me." Oh how the Chelsea faithful wish they could say the same, but they couldn't!

Jose Mourinho was kind of faultless maybe with this one, but the steep decline was so bad that this had to be right up there with his worst signings. Didier Drogba and Kezman both played as strikers for Jose Mourinho at Chelsea, and that is the first and last thing they have in common.

Seven goals in 41 appearances for £5 million in 2004 that does not seem very bad. Except it was the goal return of a striker who, with Dutch side PSV Eindhoven, scored 105 times in 122 appearances. He stayed in Jose Mourinho's camp for only one season as the Portuguese realized that Kezman did not have it in him to deal with Premier League defenses.

#1 Asier Del Horno

Asier Del Horno was reckless in defense and made panic tackles

We reckon Jose Mourinho's reluctance to invest in one-season wonders must have started from here. Asier Del Horno was a bright left-back at Athletic Bilbao who went on to make nearly 140 appearances for them. He was known for being a threat going forward and was pretty useful in the final third.

Jose Mourinho put in an effort to bring Ashley Cole in from Arsenal but that was delayed by a year, so the temporary fix was Del Horno. However, when Chelsea splashed around £10 million on the Spanish, it was thought that he could be a good long term option, except he wasn't.

He came on the back of a successful season where he scored three goals in La Liga and assisted another four. Although he was good at going forward, his ability to defend was always questionable and he frequently put in reckless tackles in panic.

He made 25 appearances for Chelsea in his first season and even won the Premier League. However, with Ashley Cole's arrival, there was no way Jose Mourinho was going to persist with a risky figure in defense like that. Del Horno is best known from his Chelsea days for hacking a 17-year old Lionel Messi and getting a red card. Good riddance to Jose Mourinho!
