Adam Phillip

Chelsea

Coombes was scouted by Chelsea while playing in the Non League for Sutton United and being offered a chance to join the Chelsea Academy. His progress continued and he was offered a two-year scholarship from the start of the 2007–08 season. The 2011–12 season started with good form shown and a reserve team goal scored in the opening month but then the highly unfortunate run of injuries continued. In August 2011, Coombes suffered a knee injury, being sidelined for six to nine months. In January 2012 Coombes signed a 12-month extension to a contract that had six months to run, and returned from injury towards the end of the season to make three substitute appearances. He was released by Chelsea with 6 months still remaining on his contract in January 2013 to give him a better chance in finding a club before those released in the summer.
