The January transfer window opened on New Year's Day with clubs dusting their cheque books to make additions to their squads.
Completesportsnigeria.com's JAMES AGBEREBI takes a look at 10 top January transfer deals in recent years…
PATRICE EVRA ( January 2006, AS Monaco to Manchester United)
Patrice Evra joined Manchester United from AS Monaco during the January transfer window in 2006 for £ 7 million.
After a shaky start, Evra went on to establish himself as one of United's and the Premier League's best ever left-backs.
Evra went on to win five English Premier League titles (2007, 2008, 2009, 2011 and 2013), two League Cups (2006 and 2010), one UEFA Champions League title (2008) and One FIFA Club World Cup title (2008).
Following a successful career at Old Trafford, Evra joined Juventus in the summer of 2014.
NEMANJA VIDIC (January 2006, Spartak Moscow to Manchester United)
Just like Evra, Nemanja Vidic also signed for Manchester United in January 2006 from Spartak Moscow for £ 7.2 million, going on to build a reputation as one of the toughest defenders in the EPL.
He formed a formidable partnership with United great Rio Ferdinand, going on to also win five EPL titles, two League Cups, one UEFA Champions League and one FIFA Club World Cup.
In the summer of 2014, Vidic left United for Italian giants Inter Milan.
DIEGO COSTA ( January 2012, loan move, Atletico Madrid to Rayo Vallecano)
Currently with EPL table toppers Chelsea, Diego Costa joined struggling Rayo Vallecano on loan in the 2012 January transfer window.
The purpose of Costa joining Vallecano was to get games in his recovery from a serious knee injury.
Costa scored 10 goals in 16 league appearances, helping Vallecano avoid relegation.
GARY CAHILL ( January 2012, Bolton Wanderers to Chelsea)
Gary Cahill joined Chelsea from Bolton Wanderers for £7 million under former Blues boss Andres Villas Boas.
That same season, Cahill helped Chelsea win the English FA Cup and also the UEFA Champions League.
The following season, he was key for Chelsea who were crowned UEFA Europa League champions.
And in the 2014/2015 season, he helped Chelsea win the League Cup and the Premier League title.
LUIS SUAREZ (January 2011, Ajax to Liverpool)
Following the sale of club favourite Fernando Torres to Chelsea, Liverpool bought Luis Suarez for £22.5 million as the Spanish replacement.
Suarez wasted no time in settling straight away into the team.
In 2012, Suarez was in action for Liverpool who broke a six-year wait for a trophy as they defeated Cardiff in the final of the League Cup.
And in 2013/2014 season, Suarez was key for Liverpool who went very close to winning the Premier League only to fall short to Manchester City with three games left.
The Uruguayan finished top scorer in the league that season before moving to Barcelona.
NEMANJA MATIC (January 2014, Benfica to Chelsea)
In 2011, Chelsea sold Nemanja Matic to Portuguese giants Benfica.
But in January 2014, Chelsea had to bring back Matic and pay £21 million for his return.
Unlike in his first stint with the Blues, Matic has been a mainstay in the team.
And in the 2014/2015 campaign, Matic was important for Chelsea who won the Premier League title and the League Cup.
MARCELO (January 2007, Fluminense to Real Madrid)
Just 18 years old, Marcelo moved from Brazilian side Fluminense to European giants Real Madrid for €7 million.
Since joining Madrid, Marcelo has gone on to become one of the best left-backs in the world.
He has gone on to win the La Liga title and the Copa Del Rey.
He also helped Madrid end their 12-year wait for their 10th UEFA Champions League title, following their 4-1 win against Atletico Madrid in the 2014 final. Marcelo scored Madrid's third goal in that final.
And in the 2016 final against Atletico Madrid, Marcelo was in action as Madrid once again saw off their City rival to claim their 11th Champions League title.
CHRISTOPH DUGARRY (January 2003, Bordeaux to Birmingham City)
World Cup and European Cup winner with France in 1998 and 2000 respectively, Christoph Dugarry joined struggling Birmingham City from Bordeaux on loan in the 2003 January transfer window.
Dugarry scored five goals in Birmingham's final six games, helping them to avoid relegation.
He completed a permanent move to Birmingham in the summer of 2003 but failed to have the same impact in the 2003/2004 season.
JAVIER MASCHERANO (January 2007, West Ham to Liverpool)
Javier Mascherano left struggling West Ham in the January 2007 transfer window for £18.
He slotted straight into the team, forming a solid partnership with Xabi Alonso in the heart of the Liverpool midfield.
Liverpool played all the way to the final of the 2007 Champions League final only to lose 2-1 to AC Milan.
He now plies his trade with Barcelona who he have gone on to win two Champions League titles.
IVAN RAKITIC ( January 2011, Schalke to Sevilla)
The Croatian midfield star left Schalke for Sevilla in January 2011 for €1.5 million.
