But seven minutes into the half, Rudy Wormer's corner was taken out by Ivory Coast quarterback Simon Delhi, who, like Tau, arrived at the club in the off-season.
It was a simple, one-of-a-kind goal that gave Bruges a major lifeline after experiencing severe pressure in the 32 degree heat in the Ukrainian capital.
Five minutes after halftime, Bruges again fell behind in much the same simple way as Vladimir Shepelev completed the effort.
Then Bruges got a major breakthrough after Dynamo defender Nikita Burda was kicked out, leaving the hosts to 10 and taking the opportunity to bring it back to 2-2 through Wormer.
At that time, Tau was rejected even by the numbers and at the moment of stopping, Kiev's hopes suddenly re-emerged after a Brandon Mechele goal.
But with almost the last touch of the game, Luis Openda leveled for Bruges to make it 3-3 and lead them into the playoffs.
