Defending champions Buriram United have taken over the top spot in Thai League 1 but their coach Arthur Papas is not happy with the way the Thunder Castle wrested the mantle from Bangkok United on Sunday night.
Buriram were made to toil at relegation-threatened Trat before they won 4-3 to surge one point ahead of the Angels in the standings.
The Thunder Castle now have 39 points from 18 games, but Bangkok United have a game in hand.
Buriram United got their goals from Dion Cools (4), Goran Causic (31, 68) and Guilherme Bissoli (80), while Thitathon Aksornsri (20), Ben Azubel (34) and Lidor Cohen (85) were on target for the hosts.
Papas said after the match: "It must have been an exciting game for the fans, but as a coach I wasn't impressed.
"We have to play better than this game. Our players know that they have to do a better job, so it wasn't a great result as far as I am concerned. We shouldn't have conceded so may goals."
In another big match, struggling Muang Thong United stunned BG Pathum United 2-0 to win their first game since the start of the second leg earlier this month.
Poramet Arjvilai put the Kirins in lead in the 39th minute before Jaroensak Wonggorn added the second from a counter-attack late in the match.
Former Thailand goalkeeper Kawin Thamsatchanan made a comeback from injury after a lapse of nearly two years in the match and kept a clean sheet for Muang Thong.
In the other match, hosts Uthai Thani drew 1-1 with Nakhon Pathom United.
