Per the Daily Mirror:
And interim Blues boss Rafa Benitez is now planning a £12million raid for his fellow Spaniard.
Benitez is seeking an out-and-out striker to give Fernando Torres the chance to rest in the second half of the season, and is also keen to land a combative and physical central midfielder.
Instead of spending transfer funds on Villa, the best decision would be to recall young striker Romelu Lukaku from West Bromwich Albion, where he has been on loan since the start of the 2012-13 Premier League season.
Lukaku is the perfect striker to push Torres and challenge him to be better. Earning some experience in the midst of a title race would also be beneficial to the Belgian striker's development, so Benitez must consider adding Lukaku to the squad in January.
If Chelsea are looking for an attacking player from La Liga to bolster the squad's depth, then Atletico Madrid striker Radamel Falcao should be the primary target.
Falcao could make a much larger difference in the title race than Villa, and would help ensure that Chelsea plays to the best of their ability against the top teams in the league.
The competition for the top four spots in the Premier League has gotten stronger this season, and Chelsea cannot assume they will qualify for next year's Champions League if they don't make a significant move in the January transfer window.
Arsenal, Tottenham and Everton all have strong squads and will challenge for a top-four finish for the remainder of the season. The Blues are currently in third place with 32 points, but have a slight two-point lead over the fourth-place Gunners.
Villa is not the type of player at this point in his career who will improve Chelsea in a meaningful way. He's no longer a world-class goal scorer.
Making a move for Villa would be a mistake by Benitez, who probably needs his club to finish the season with trophies if he is to remain as club manager for next season.
