Prapon Pongpanich was sacked in the middle of the season and replaced by former Thailand national team head coach Thongsuk Sampahungsith. The club finished in ninth place out of sixteen in the final standings.

Breath of Buriram (2010–2013)

In December 2009, it was announced that a politician based in Buriram, Newin Chidchob was to take over the club. He had already tried unsuccessfully to take over TOT SC and Royal Thai Army Newin relocated the club to Buriram in Isan and rebranded it to Buriram PEA Football Club. Buriram PEA inherited most of the players from the former PEA club including the stars like Rangsan Viwatchaichok, Apichet Puttan and Theerathon Bunmathan. Pongphan Wongsuwan who was a long-time head coach of TOT SC was instated as a coach. Thailand national team member Suchao Nuchnum of TOT SC also followed his coach to the new team.
