The Spaniard is ready to be a Blues player.
Chelsea are set to finalise their first transfer of the summer as Atletico Madrid striker Diego Costa completes medical ahead of a £32m deal, reports BBC Sport.
The 25-year-old will come in to bolster a Blues attack that manager Jose Mourinho has bemoaned in recent times – with the striking trio of Demba Ba, Samuel Eto’o and Fernando Torres all failing to impress in 2013/14.
On the contrary Costa had a brilliant last campaign, top-scoring for Atleti with 37 goals in all competitions as Diego Simeone’s men won their first La Liga title in 18 years and reached their first ever Champions League final.
This all came after the sale of Radamel Falcao 12 months ago, when the Colombia international left the Vicente Calderon Stadium in a £50m deal to join AS Monaco.
The loss of Falcao was considered devastating to many fans, but the form of Costa has arguably improved Atletico despite selling their best player and now the forward is regarded among the best in world football.
The attacker was born in Brazil and made two appearances for the nation in friendly internationals, before changing his allegiances to Spain this year.
FIFA rules specify that a player can do this as long as they haven’t played a competitive match for the original country and having lived in Madrid for longer that five years Costa qualifies as a Spanish citizen.
National team manager Vicente Del Bosque has included the striker in his 23-man squad for the 2014 World Cup, which starts on June 12.
