Jonas Elmer (born 28 February 1988 in Zurich, Switzerland) is a full-back or winger who formerly played for Chelsea's Academy team.
Jonas joined Chelsea in 2005 as a first-year scholar from Swiss club side Grasshoppers.
Jonas' versatility allowed him to feature at full-back or on the left wing and his physical ability quickly allowed him to move through the ranks at Stamford Bridge.
He signed a professional contract with the Blues in 2006 and appeared in three first-team pre-season friendlies but never got the opportunity to make the step up permanently and departed in 2007 in search of regular football.
Jonas represented Switzerland at all major junior levels up to Under-21, where he earned six caps; the first of which was whilst he was a Chelsea player.
