Chelsea’s January transfer window: The 5 players that could secure the Blues the title

Diego Costa – Atletico Madrid

According to the Mirror again, Chelsea could battle Arsenal for former Liverpool target Diego Costa.

The striker has been on fire this season, establishing himself as one of the very best in the business. His 19 league goals sees him level with Liverpool’s Luis Suarez as Europe’s top marksmen, ahead of both Cristiano Ronaldo and Lionel Messi.

Costa works hard, is an incredibly powerful physical presence, and can finish off either boot. Atletico would likely demand an astronomical fee, but they have shown in the past with the sales of Fernando Torres, Sergio Aguero and Radamel Falcao that they are willing to sell their best players should a side come in with an appropriate offer.
