Premier League winner with bite
Chelsea signed Costa from Atlético Madrid in 2014. In his first season, he scored 20 Premier League goals and helped the club win the title under José Mourinho. They then achieved another league victory in 2016–17, this time under Antonio Conte, where he again finished as a key attacking figure.
Costa's style divided opinion throughout England. He was combative, physical and tireless. Still he was decisive. He scored important goals in big matches and gave Chelsea the edge they often lacked in tight matches.
Overall, he won two Premier League titles and one League Cup with the Blues. In all competitions, he scored 59 goals in 120 appearances. This return underlines how central he was to Chelsea's success during that period.
From Stamford Bridge to the Broad Forum
After leaving Chelsea in 2018, Costa returned to Atlético Madrid. He later had stints in Brazil with Atlético-MG, Botafogo and Grêmio. His last official appearance took place in late 2024.
Nevertheless, his prime years were in the Premier League. Despite being born in Sergipe, Brazil, he represented Spain at the 2014 and 2018 World Cups.
A mark in Chelsea's recent history
Time has softened the edges of the controversy surrounding his Stamford Bridge exit. All that remains are silver vessels and tablets.
Costa was not subtle. He was not universally loved outside West London. However, during their peak, they embodied a ruthless Chelsea team built to win at any cost.
For a club that is struggling to find long-term stability, his retirement also serves as a reminder. Reliable, title-winning numbers of nine are rare. Chelsea had one in Diego Costa - and they knew it when he was at his best.
