Head coach Totchtawan Sripan was delighted with how Bangkok stuck to the gameplan, saying his players showed great composure to neutralise Gamba's aggression.

Such was Gamba's dominance that they had almost seventy percent of possession, with 21 shots to just eight for Bangkok. Crucially, Bangkok limited Gamba to just two attempts on target as Totchtawan's side weathered the storm to carve out the narrow win.

The head coach, however, is fully aware that it is only a half accomplished mission and will prepare his players to brace for a wounded Gamba at the Rajamangala Stadium.

Gamba head coach Jens Wissing wasn't overly concerned about the defeat, saying his side were fully in control of the first leg and expecting his players to rebound emphatically.

Wissing, however, admitted that his team were not at their best and lacked sharpness in front of goal.

He felt Gamba had done better in the second half and having had a week to iron out the weaknesses and mistakes, will head into the return leg confident his side will progress to the final.
