Atletico Madrid striker Diego Costa is all set to complete his £32 million move to Chelsea after reportedly completing his medical at Stamford Bridge.

The Blues, who have not had a prolific striker since the departure of Didier Drogba in the summer of 2012, have reportedly met the 27-year-old's buyout clause to lure him out of the Vicente Calderón.

According to a report in Goal, Costa, who currently earns £50,000-per-week at Atletico Madrid, is set to triple has salary by signing a five-year deal worth £150,000-per-week.

Chelsea reportedly want to complete the deal before the start of the 2014 World Cup, where Costa is expected to feature for Spain if he recovers from a hamstring injury in time.

The Brazil-born striker, who scored 27 goals from 35 appearances in the La Liga last season, the third best behind Real Madrid's Cristiano Ronaldo (31) and Barcelona's Lionel Messi (28), emerged as Chelsea's top transfer target after he helped Atletico Madrid win the Spanish League, their first since 1996, and reach the final of the Champions League.

Chelsea boss Jose Mourinho was reportedly keen to sign the Spain International in the January transfer window itself. However, the deal fell through after Costa refused to move to a new club in mid-season.

The Portuguese boss, who has time and again complained about the lack of quality of the Chelsea strikers - Samuel Eto'o, Demba Ba and Fernando Torres - believes the Blues will prove to be genuine Premier league title contenders next season with a world class attacker amongst their ranks.

Although the Blues were on course to win the Premier League title in February, defeats against small sides including Aston Villa, Crystal Palace and Sunderland hampered their chances.

Many believe these defeats resulted due to the lack of goals from the Chelsea strikers, who were only able to score 19 Premier League goals among themselves last season. This is why Mourinho is keen to get a star striker at Stamford Bridge this summer.

Meanwhile Mourinho's dealings with Atletico Madrid may not have finished as he is also interested in getting Filipe Luís and Tiago.

While Luís is being targeted as a replacement for the Blues' departing left-back Ashley Cole, Mourinho is eager to get Portuguese midfielder Tiago, who played for Chelsea during the 2004/05 season, as he is available on a free transfer.

Also, Belgian goalkeeper Thibaut Courtois, on loan at the Vicente Calderon for the past three seasons, is likely to play for Chelsea next campaign as Atletico Madrid signed a new goalkeeper, Miguel Moya from Getafe, on Wednesday.
