January is renowned for it's transfer window. Good signings are made and bad signings are made, with a varying degree of money spent. Bargains are found and players are bought for different reasons: either to stabilise a team, rescue them from relegation or help push for the league title.
Below are three January signings from the last few years who have gone on to make a positive impact in the Premier League.
Suarez caught the eye of then-manager Kenny Daglish and has never looked back since. Aside from his disciplinary problems and the biting incident last season, Suarez must be considered one of Liverpool's greatest ever signings.
The Uruguayan has flourished more recently under Brendan Rodgers' style of play which has led to a deadly partnership with Daniel Sturridge. Despite being linked with Real Madrid last summer, Suarez signed a new long-term contract with the club last month.
Asmir Begovic (Portsmouth to Stoke - January 2010)
Since joining Stoke in 2010, Begovic has become one of the most consistent goalkeepers not only in England, but in Europe too. His clean sheets were what Tony Pulis' style of play were built around and even saw the Potters make it to an FA Cup final and the Europa League.
The towering goalkeeper's career at Stoke could be coming to end soon, though. New 'keeper Jack Butland is knocking on the door of the first-team and Begovic could presumably be forced out under new manager Mark Hughes.
Nemanja Vidic (Spartak Moscow to Manchester United - January 2006)
Vidic has become a household name around the world for his commanding displays at the heart of the United defence. He has grown both as a player and as a leader and became captain under Sir Alex Ferguson at Old Trafford.
The Serbian is now faced with a different challenge at the club. With the transitional period well underway with David Moyes the question is will Vidic be involved or not? One thing is for sure, Vidic will be classed as legend at the club for his role in the side since his arrival.
Clint Dempsey (New England Revolution to Fulham - January 2007)
One of Chris Coleman's signings and he was certainly a risk considering the American had only played in his native division - but what a risk it turned out to be. The all-action midfielder proved to be a big hit with the Fulham fans following excellent displays in the league and Europe.
Dempsey has even re-joined the club on loan now after spells at Tottenham and Seattle Sounders and is helping the club fight relegation.
Daniel Sturridge (Chelsea to Liverpool - January 2013)
The England striker arrived on Merseyside with a turbulent past, after beginning his career at Manchester City he then departed for London and Chelsea. A loan spell at Bolton really gave Sturridge the Premier League experience he needed, and, with eight goals in 12 games, he helped the Lancashire side stay in the league.
After returning to Chelsea, Sturridge was deployed as a winger and he was clearly unhappy at the progress he was making. A move to Liverpool in January 2013 followed and his career has flourished since.
Now a regular in the England side, Sturridge has formed an, at times, unstoppable partnership with Suarez as Liverpool look to win their first league title since the 1989-90 season.
