Frenchman Mathias joined the Dons from Plymouth Argyle in August 2009 and was one of four signings made by the Club 24 hours before the season's opening fixture. Equally capable in central defence or at right-back, his versatility make him a valuable asset.

A pacy and powerful central defender, Mathias started his career with French giants Paris St Germain before joining Hibernian in October 2001, where he established himself at the heart of the Hibs defence.

While at Easter Road he forged a strong relationship with manager Bobby Williamson, so when the former Scotland international was handed the reigns at Plymouth, it came as little surprise that Mat followed him south of the border in June 2004.

Having made the switch to Home Park, Doumbe quickly earned the favour of the Green Army, and by the start of the 2008/9 season he was the Devon club's longest serving player.

After a mixed final season which saw the Pilgrims fighting relegation from the Championship, Doumbe opted for a move to MK where he quickly showed himself to be an important cog in the defensive machine.
