Chelsea finally confirmed moments ago that Spanish international hotshot Diego Costa has signed a five-year contract with the Blues and is ready to start working with Jose Mourinho at the club's pre-season training camp in Austria as early as next week.
Costa has been chosen by Mourinho as the man to lead the line at Stamford Bridge next season, with Chelsea agreeing to meet his £32.5m release clause after a remarkably consistent season in La Liga with Atletico Madrid.
New star striker
The 25-year-old was nothing short of sensational last season, scoring a magnificent 36 goals in all competitions to help Atletico win La Liga and very nearly complete an amazing Champions League success.
Costa fell someway short of matching that clinical form at the World Cup for Spain, but in fairness was carrying an injury into the tournament and was far from the worst performer in a nightmare tournament for La Roja.
The Brazilian-born hitman's focus is now on delivering the goods for Chelsea next season, with his input sure to have a massive impact on whether Mourinho can deliver trophies after an encouraging but ultimately disappointing first season back in charge.
Targeting instant success
In his first official interview as a Chelsea player Costa told the club's official website: ‘I am very happy to sign for Chelsea. Everybody knows it is a big club in a very competitive league, and I am very excited to get started in England with a fantastic coach and team-mates.
"Having played against Chelsea last season I know the high quality of the squad I am joining.
‘I would like to thank everybody at Atletico who made me into the player I am, it was an incredible time for me, but now I am starting a new adventure and I hope to win many trophies with Chelsea."
La Liga duo ready to shine in West London
Chelsea fans will be relishing the prospect of watching Costa make his Chelsea debut, although they did see the prolific marksman score from the penalty spot for Atletico in last season's Champions League semi-final second leg at the Bridge.
His arrival marks the second major summer signing Chelsea have managed to conclude and both arrive from La Liga, with Costa joined in the Blue part of London by former Arsenal captain Cesc Fabregas.
Both men will be charged with spicing up an attack that largely failed to deliver last season, with Fernando Torres, Demba Ba and even the experienced Samuel Eto'o failing to convince Mourinho they had what it took to drive Chelsea to success from the front.
A relatively kind first two fixtures could give Costa and his new playmaker supreme to get off the mark quickly in Chelsea colours, beginning with an opening-weekend trip to newly-promoted Burnley on August 18th.
