We're now well into the mid-season transfer window and clubs across the Premier League are looking for new players to help them in their individual battles this season. At the top of the table it is still extremely close. Arsenal currently lead the way, swiftly followed by Manchester City and Arsenal. Liverpool can't be ruled out yet and Tottenham could mount a late challenge, while it would be daft to write off defending Champions Manchester United at this stage. The difference this season could be made by the January transfer window. Pundits have identified the need for signings in certain areas for all of the top teams and each manager will have their own ideas of exactly what they are looking for. It's very tight at the moment and the deciding factor on who comes out on top may just be down to who performed best in the transfer window. Every team is ready to splash the cash and they all have funds available, it's all about making sure the money is spent in the right ways and on the right players. The January transfer window has brought some brilliant players to the Premier League over the years including Luis Saurez' arrival in Liverpool and the big money departure of Fernando Torres to Chelsea. It also can't be forgotten that this was the month Manchester City first flexed their financial muscles and brought in Brazilian star Robinho. New signings can take a while to settle but the six following players are ready to rip up the Premier League. Time will tell whether these players will come to our shores but there's no doubt that they could all be great players in the best league in the world.
