When Saarelma was 16, he was spotted by the scouts of English club Chelsea, playing for his youth club FC Lahti. After a successful trial with the club, Saarelma was offered a two-year contract in the beginning of 2005, and officially moved to the club in the summer of 2005. In the beginning of his Chelsea career, he formed an important part of the club's youth team and helped the team to reach the final of the famous tournament, Milk Cup, where they lost to FC Barcelona. After two seasons, Saarelma left the club, where he was highly praised for his skills with the ball, but as a small player, could not really cope with the physical side of the game, which is an important part of the English football.

He won the Estonian Cup and Super Cup with Levadia in 2010. Saarelma left the club before the 2011 season began and moved to Swiss 1. Liga club FC Baden.
