Yes, it’s that time of the year again and the January transfer window is in full swing. Chelsea manager Jose Mourinho is busy making some additions to his squad in an attempt to wrestle back the Premier League crown.

The mid-season window is notorious for its last minute, inflated purchases, but the Blues have had some success since FIFA made transfer windows compulsory during the 2002-03 season.

Here at getwestlondon, we have been asking readers via Twitter for their suggestions of Chelsea’s top five best and worst winter buys. Last night we featured your favourite January recruits , so now here’s the bottom five according to our followers.

1. Fernando Torres from Liverpool 2010-11

Fernando Torres remains Chelsea’s most expensive player having moved to west London from Liverpool on a dramatic transfer deadline day in January 2011. Torres is a player who has divided opinion among Blues supporters, indeed he also incredibly featured in yesterday’s list of Chelsea’s best January buys, although he received far more votes for this category.

However his trophy haul speaks for itself. Having won the World Cup and European Championship with the Spanish national team, Torres sealed Chelsea’s spot in the Champions League final with a goal against Barcelona in 2012. The Blues went on to win the competition and a year later the Spaniard conquered Europe again as he helped his side pick up the Europa League.

Torres has scored eight times in 22 games for Chelsea this season.

2. Ricardo Quaresma from Inter Milan 2008-09

Ricardo Quaresma is the only loan signing in this list. Despite only having a brief stint in SW6, the Portuguese winger made a lasting impression on the Stamford Bridge faithful - and it wasn’t a good one.

He was omitted from Inter’s squad for the knockout stages of the Champions League in the 2008-09 season and Blues boss Luiz Felipe Scolari offered him a lifeline in the Premier League. But ‘Big Phil’ will have wished he hadn’t bothered as Quaresma, who was tipped for superstardom while alongside Cristiano Ronaldo at Sporting Lisbon, made just five appearances and failed to hit the target.

Quaresma signed up for a second spell at Porto at the turn of the year after a stint in Dubai.

3. Jiri Jarošík from CSKA Moscow 2004-05

Czech international Jirii Jarošík was arrived from CSKA Moscow for the rather modest transfer fee of £3million on 6 January 2005. A month later and he found himself in the starting line-up for a League Cup final with Liverpool, securing his first piece of silverware, and later that season added a Premier League winner’s medal to his collection.

But he was struggling to cement a regular spot in Jose Mourinho’s powerful midfield engine room and at the start of 2005-06 he was loaned to Birmingham City, eventually signing for Celtic in 2006.

Now aged 36, Jarošík has played in Spain with Deportivo Alavés since last summer.

4. Scott Parker from Charlton Athletic in 2003-04

Scott Parker wowed Premier League crowds in the first half of the 2003-04 season with his tenacious tackling and long-range shooting ability. He had become the linchpin of Charlton’s midfield and Chelsea manager Claudio Ranieri, keen to add English talent to the ranks at the Bridge, paid £10million to sign him in January 2004.

It was a step up in class for Parker though, who now found himself warming the bench as cover for the sensational Claude Makélélé and Frank Lampard. Despite chances being limited at Chelsea, Parker had still done enough to secure the PFA Young Player of the Year award that season.

Parker was to fall further down the pecking order the following season before being sold to Newcastle United in July 2005. He now plays for Chelsea’s derby rivals Fulham.

5. Demba Ba from Newcastle United 2012-13

Senegal international Demba joined Chelsea from Newcastle United on 4 January 2013 and made an instant impact, getting on the scoresheet twice for his new club the following day as Chelsea knocked Southampton out of the FA Cup.

But he's struggled to make an impression at Stamford Bridge since that explosive debut and has fallen behind Fernando Torres and Samuel Eto’o since the arrival of Jose Mourinho in the summer.

The 28-year-old forward, who could well leave the club during this January transfer window, has scored three times in 14 outings this season.
