Davis Cup - Djokovic sends final to decider
Djokovic completed a 6-2 6-2 6-4 victory to the delight of the vast majority of the near 17,000 crowd and put the hosts on the verge of their first Davis Cup final triumph.
To thicken an intriguing the plot still further both team captains then changed their expected line-ups for the second reverse singles which will decide the tie.
Monfils, who had given France a 1-0 lead on Friday by outplaying Tipsarevic, was no match for a fired-up Djokovic who celebrated his victory like a triumphant prize fighter, legs apart and fists clenched, bellowing at the crowd.
"You have to make noise to silence the French fans," an emotional Djokovic implored the crowd. "We are at home, we have to make it count now."
"This is one of the best matches I've played in my career in the circumstances," added the world number three.
"I have a lot of respect for all the French players, especially Gael who is a long-time friend."
Djokovic, who won both his singles without dropping a set, was dominant for two sets but had some alarms in the third when Monfils relaxed and started striking massive forehands.
Monfils broke to lead 4-3 with a scorching winner which prompted Djokovic to destroy his racket frame in rage but the Serb regained his composure to hit back and clinch victory in little more than two hours.
Despite a deafening noise from the packed stands, which also contained 1,200 travelling French fans kitted out in all blue and holding aloft giant tricolours, there was no repeat of the bad feeling which at times marred Saturday's doubles.
