Chelsea have made Atletico Madrid striker Diego Costa their number one transfer priority this summer, according to reports.
Metro claims Jose Mourinho has set his sights on the Real Madrid target, and the club believe they are in pole position to land the player at the end of the season.
The paper goes on to claim the Blues value the player at £27million - below his minimum fee release clause - and will open negotiations with the La Liga club before the World Cup in Brazil.
Chelsea have a good relationship with Atletico, the report claims, helped by the back-to-back loan deals for goalkeeper Thibaut Courtois at the Vicente Calderon Stadium.
And, with the Premier League title chasers looking to bolster their attack at Stamford Bridge, Costa has shown he has the pedigree to score goals in Europe as well as domestically.
Fernando Torres, Samuel Eto'o and Demba Ba are currently vying for oppotunities for Chelsea up-front, but none have made the position their own under 'the Special One' in west London.
Roman Abramovich faces competition to add him to the ranks though, as Real Madrid keep a close eye on the 25-year-old as he makes his mark for their neighbours.
Whilst Los Blancos boast one of the best squads in Europe, manager Carlo Ancelotti isn't flush with options in attack at the Santiago Bernabeu.
And, if Costa joined the ranks at Real Madrid, they'd be a force to reckon with in the Champions League particularly.
