Bangkok United maintained their perfect record in Thai League 1 to pile pressure on defending champions Buriram United ahead of the northeastern giants' clash with Pathum United on Sunday.
The Angels endured some tough time before taming Nakhon Ratchasima 3-0 at home on Saturday.
A 41st-minute goal from Mahmoud Eid and late strikes by Suphan Thongsong and Heberty Fernandes gave Bangkok United their fourth victory in as many games.
On Friday night, Ratchaburi won their fourth straight match with a 2-0 victory over hosts Nongbua Pitchaya.
Derley and Alvin Fortes were on target to help Ratchaburi pick up three points.
The result is likely to put Nongbua coach Thawatchai Dumrong-ongtrakul's job in peril, but he was defiant after the loss.
"The decision about my future will be taken by me. Right now, I am the head coach and I hope that the team will bounce back," he said.
"If the team continue to fail, I will accept the responsibility and won't prolong my stay at the club."
