Speaking to the press ahead of the second match in Group C of Asia Zone qualifying, Polking admitted he could be fired if Thailand’s bid for 2026 World Cup qualification ends in defeat tonight.
Thailand lost their opening qualifier 2-1 to China in Bangkok last Thursday.
Next up for the War Elephants is Singapore, who were crushed 5-0 by South Korea in their Group C opener last Thursday.
"It's a game we can't underestimate because they lost in the first game,” Polking said.
“Certainly, it's their last chance, and it's a dangerous game for us as well. However, we are confident about making a comeback. We'll face it head-on and try again.
There is no time to dwell on the game against China because we need three points in this game.
"That's what we are focusing on."
Thailand manager Nuanphan Lamsam, aka “Madam Pang”, said the national team must bounce back to keep their chance of qualifying for the next round alive. She said everyone was ready to fight while urging Thai fans to get behind their team.
"Despite disappointment from the recent game against China, everyone's spirit is still high and we are ready to rise and fight.
We know there is still an important game against Singapore waiting for us. We hope Thai football fans will continue to support us because … everyone is motivated and ready to face the upcoming challenge against Singapore.”
The Thailand-Singapore match kicks off at the National Stadium in Singapore at 7 pm tonight, Thai time. The match will be broadcast live on Thai Rath TV.
