Diego costa trains on beach while chelsea are on pre season tour in singapore

It seems like you're referring to a specific news article or incident involving Diego Costa, a former Chelsea FC player, and the club's pre-season tour in Singapore.

To clarify, Diego Costa did indeed train on a beach while Chelsea FC was on their pre-season tour in Singapore in 2015. Costa, who was a key player for Chelsea at the time, had been involved in a public spat with the club's manager, Jose Mourinho, and had been left out of the team's pre-season tour.

As a result, Costa decided to train on his own on a beach in Spain, rather than joining the team in Singapore. This move was seen as a way for Costa to maintain his fitness and prepare for the upcoming season, despite not being part of the team's official pre-season preparations.

It's worth noting that Costa's decision to train on his own was met with some criticism from fans and pundits, who felt that he was not showing the right attitude and commitment to the team. However, Costa ultimately returned to the team and went on to have a successful season with Chelsea, scoring 20 goals in the Premier League and helping the team win the title.
