Why Chelsea should abandon £12m Atletico bid - and who they could target instead

Chelsea are reportedly set to make a final £12m offer for Atletico Madrid left back Filipe Luis – still £7m short of his release clause.

The Blues need to snap up a left back this summer after allowing long-serving Ashley Cole to leave on a free transfer, and the 33-year-old will now join Serie A side Roma – leaving Chelsea with a big hole to fill.

For the past month, their primary target has been Brazilian international Filipe Luis, who enjoyed a superb season with Diego Simeone's La Liga title-winning Atletico Madrid side, but somehow failed to break into the Brazil squad for this summer's World Cup.

His impressive displays in the Spanish capital have attracted interest from Chelsea, but the two sides are having major disagreements over the transfer fee for the former Deportivo man. Atletico want Chelsea to pay Luis' £19m release clause, but the Blues have reportedly made a final £12m bid to sign him - and won't be increasing their offer.

At almost 29 years old, Luis may only have three or four years left at the top of his game. With that in mind, it's hard to really justify splashing out almost £20m just to bring him to West London, even before wages, agents fees and a signing on fee. Instead, Jose Mourinho has to look to the future, and in doing so, target younger left backs.

The likes of Sporting Lisbon's Marcos Rojo and Sevilla's Alberto Moreno have been linked with moves to Stamford Bridge, but their attention should be on Swiss international Ricardo Rodriguez, who impressed at the World Cup. At just 21, the Wolfsburg man is one of the top young left backs in world football, and his displays in Brazil showed that he is capable at both attacking and defending.

A £12m fee is reportedly on Rodriguez's head - the same price that Chelsea are willing to play for Luis. Seven years younger than the Brazilian and with bags of potential, Rodriguez is the man that Chelsea should be pursuing - not Atletico star Luis.
