Atletico Madrid have joined the chase to sign Jackson Martinez, which will open the door for Chelsea to land Diego Costa, according to the TalkSport website
Martinez has been nothing short of sensational since his £7.7million to Porto from Chiapas in 2012, scoring 53 times in 80 matches for the Portuguese team.
A number of clubs have been linked with a big time move, but it seems Atletico are primed to land the free-scoring Colombian, and that in turn suggests that Costa could be on his way out of the Vicente Calderon.
The fearsome Brazil-born striker has scored 29 goals in all competitions this term and Chelsea boss Jose Mourinho is keen to activate his £34 million clause and bring him to the Premier League.
The Portuguese boss is looking to add a bit more fire-power to the squad and knows Costa would be one of the best buys of the summer
