Chelsea striker Diego Costa jetted out to Ibiza following his team's opening Premier League game at the weekend to watch DJ Avicii perform.
The 26-year-old, who was dogged by injury problems last season, played the entire 90 minutes of the Blues' 2-2 draw with Swansea City at Stamford Bridge on Saturday.
The following day, the Spain international was spotted at open-air club Ushuaia to watch Avicii's set, and he also posed for photos with support act Benny Benassi.
Manager Jose Mourinho is believed to have given the players two days off before they begin preparations for this weekend's clash against Manchester City at the Etihad Stadium.
