Finally, it must be relegated to play in Ngor Royal Cup in season 2004–2005 by returning to its original name but it was not as successful as it should be.

In 2007 Siam Sport Syndicate by Rawi Lohtong, the President of Siam Sport Syndicate bought the club and changed the name to Muangthong United Football Club and moved to a new ground at Muang Thong Thani, Thunderdome Stadium.

After their tournament exit Henrique Calisto, the club's manager, was sacked and Fowler took over as player/coach of Muangthong United.

In 2012, Muangthong engaged an unbeaten run which lasted the whole season, and Teerasil also scored four goals in a single match, an 8–1 routing over BBCU on 18 October.

After his impressive goal tally in the season, Teerasil was invited by La Liga sides Atlético Madrid and Getafe for a trial, but as the former was a Muangthong partner, he headed to Atlético Madrid in January 2013; he also attracted interest of Trabzonspor in June.

[27] The Muangthong United Academy (MTUTD Academy) has a clear aim of providing a place to pursue and achieve success through a first-class coaching environment for all the young players registered in its system to produce players that will play and succeed in the first team at Muangthong United.

Due to the success of the club and the increasing number of spectators, the stadium was built with steel tube stands with 15,000 seats during the 2008 season.

In 2016 the fans of these 2 teams were making riot it again in the same area this event made the Football Association of Thailand introduce measures for something to solve this problem.

[45] The rivalry with Buriram United arises from the numerous times the two teams, as well as Buriram United represented as rustic people and Muangthong United represented as urban people, In the same sides these two teams represent two different politics party sides in Thailand that sent their members to elect presidents of the Football Association of Thailand, have battled for the Thai League 1 title this fixture has become known as one of the finest Thai League match-ups in history.

I want to congratulate Muang Thong United for winning the Thai Premier League for the second consecutive year this is a sign of the good work the club is doing.
