[4] Nevertheless, he won a contract at Paris Saint-Germain and was capped by the French under-21 team against Romania, only to be shown the door at the Parc des Princes after picking up a serious ankle injury.
[6] In August 2003, it was reported that Dundee United boss Ian McCall had offered a cash sum plus David McCracken in exchange for Doumbé.
[9][10] Doumbé turned down a three-year deal at Hibernian when he joined his former manager Bobby Williamson at Plymouth Argyle on a free transfer in May 2004.
[12] Days after being linked with a move away from Home Park, he was described by Williamson as being "very committed and very brave, or foolish, whatever way you want to look at it" after he required 24 stitches in his head after challenging for the ball in a 2–1 defeat to Leicester City at the Walkers Stadium.
[13] He firmly established himself in the first team in the 2005–06 campaign, making a total of 43 Championship appearances as new boss Tony Pulis focused on shoring up the defence.
Doumbé featured just 14 times for the "Pilgrims" in the 2007–08 season, with Paul Sturrock (yet another new manager) generally preferring the central defensive partnership of Marcel Seip and Krisztián Timár.
[15] Loan signing Craig Cathcart was generally preferred to play alongside Marcel Seip in the 2008–09 season, limiting Doumbé to 24 appearances.
[20] He went on trial at Port Vale in July 2013, but did not sign a contract; manager Micky Adams said that "It's well documented that I would have liked to have brought in Matt Doumbe, but that's not been possible.
[24] Doumbé was used regularly in central defence as Northampton's form improved after new manager Chris Wilder arrived at Sixfields in January.
