The 15 most important signings of the January transfer window

Rafinha (Inter Milan)

The Barcelona midfielder moved to Italy on loan in a bid to relaunch his career after coming back from a lengthy spell out with a knee injury.

Carlos Tevez (Boca Juniors)

After a year in China, Tevez returned home with the former Manchester City man hoping to fire his side to Copa Libertadores glory.

Aymeric Laporte (Manchester City)

Pep Guardiola paid €65m for the Athletic Bilbao man to make his City's club-record signing. Such a fee will naturally attract pressure but the Frenchman crusied through his debut against West Brom just 24 hours after signing.

Virgil Van Dijk (Liverpool)

Liverpool made the Dutchman the most expensive defender in history when they paid Southampton €84m for his services, with the fee attracting criticism in some parts.

Lucas Moura (Tottenham)

Having fallen down the pecking order at the Parc des Princes it was time for Moura to move on. With his directness and pace in attack he looks to be a good fit for Spurs' style as they look to ensure Champions League football again next season.

Henrikh Mkhitaryan (Arsenal)

The Armenian left Manchester United as part of the Alexis Sanchez deal, with Arsene Wenger now hoping the playmaker can add some inventiveness to Arsenal going forward.

Alexis Sanchez (Manchester United)

Without doubt one of the biggest deals of the window. The Chilean looked set for a move to Manchester City, only for them to pull out over

Yerry Mina (Barcelona)

Having replaced the long-serving Javier Mascherano, the Colombian has big shoes to fill. However, having gained a reputation as one of South America's best defenders that shouldn't be too much of a problem.

Iñigo Martinez (Athletic Bilbao)

A controversial move as Athletic Bilbao raided neighbours Real Sociedad for the Basque defender following Aymeric Laporte's departure. Having previously been linked with Barcelona and Manchester City, Martinez is certainly a player that is rated by Europe's elite, making the signing something of a coup.

Michy Batshuayi (Borussia Dortmund)

The 24-year-old headed to Germany in search of game time after falling out of favour under Antonio Conte at Chelsea.

Marc Bartra (Real Betis)

The Spaniard returned to his homeland with Betis after only featuring sporadically during his time with Borussia Dortmund.

Olivier Giroud (Chelsea)

The target man moved across London to Chelsea to provide an experienced alternative to Alvaro Morata following Pierre-Emerick Aubameyang's switch the the Emirates.

Hector Moreno (Real Sociedad)

The Mexican arrived at the 'Anoeta' in search of minutes ahead of the World Cup this summer.

Pierre-Emerick Aubameyang (Arsenal)

The Gabonese arrived as a big-name replacement for Alexis Sanchez as Arsenal looked to cushion the blow of losing their star man.

Philippe Coutinho (Barcelona)

They got their man in the end. Coutinho finally made his move to the Camp Nou after Liverpool accepted an offer worth up to €160m. Big things are expected of the Brazilian, who is seen as a long-term successor to Andres Iniesta.
