Now this is a deal that many have questioned, but you cannot deny that Bony has proven his ability at the very top level. The Ivorian possesses the pace, power and ability to cause endless problems for any defender. The former Swansea man may not play as much as he fights for a place with Aguero and Dzeko but he will certainly be a fantastic option for the current champions.
It may have taken until deadline day for Chelsea to get their man but Cuadrado should be worth the wait. The playmaker became the centre of attention at the World Cup and has been on the radar of the top club sides since. Adding a player of Caudrado's quality to the likes of Hazard, Costa and Fabregas is very scary for the rest of the Premier League.
After losing Destro to Milan, Roma needed to find themselves a new goal getter. In Seydou Doumbia they've definitely found one. Doumbia's career has taken off since moving to CSKA Moscow in 2010 scoring an impressive 84 goals in 130 games including three memorable Champions League goals earlier this season against Man City.
During his three and a half years at Benfica, Enzo Perez was part of a side that won numerous trophies and was also a part of the Argentina side that reached the World Cup final. The 2014 Primeira Liga Player of the Year could prove a huge asset in the middle of the park for Valencia as they look to join the La Liga elite.
The versatile Italian was another touted for various top clubs. Rafa Benitez managed to secure the forwards services and Gabbiadini and is delighted to have signed a player who is capable of doing everything. Another great January signing.
Dortmund's season has really been abysmal. Kampl was brought in to try and freshen up Klopp's options and turn their season around. The Slovenian attacking midfielder has proven his technical ability during his time with Salzburg and hopes to emulate that form to claw Dortmund away from the relegation battle they find themselves in.
The all round midfielder is one of the real hot prospects in football. The Brazilian wonderkid will more than likely be a bit part player for the rest of this season but has all the qualities to become a superstar over the next few years at Real Madrid. With an impressive shot and a great range of passing.
Arsenal needed to strengthen at the back, everyone was aware of that and Gabriel Paulista could be the player to make that happen. Paulista is a determined defender who looks to steal the ball from his opponents and does so successfully. The quick centre half who reads the game as good as any could be huge cog in the Arsenal machine as they look to drag themselves back into the Premier League elite.
Schurrle's move to Wolfsburg may be seen by some as a step backwards for the World Cup winner but we're not so sure. Wolfsburg are making a real statement. Signing a player of Schurrle's quality shows that they are heading in the right direction to compete with Bayern at the top of the Bundesliga.
Plenty of teams were after the Swiss superstar. It came as a bit of a surprise when Shaqiri chose Inter after various opportunities arose with top teams from around the world, but Inter have really got a player. Shaqiri really impressed at the World Cup and will be vital if Inter are to compete at the top of Serie A in the near future.
