Spain striker Diego Costa has signed a five-year contract with Premier League giants Chelsea today, for a reported fee of £32 million. The 25-year-old helped Atletico Madrid capture their first La Liga title in 18 years this past season, as well as a birth in the Champions League final. In total, Costa scored 64 times in 134 appearances for Atletico Madrid, and Chelsea boss Jose Mourinho will look to Costa to solve Chelsea's goal-scoring woes of last season.
