Jose Mourinho and Didier Drogba were part of a star-studded ensemble honouring the 36-year-old, who ended his playing career last year.
"It is all so overwhelming for me," he said. "I had planned on not crying, but it is not so easy."
His 'Ballack and Friends' team defeated a World XI, coached by new Chelsea manager Mourinho, 4-3, with Ballack himself netting twice.
Germany coach Joachim Low was also present at Leipzig's World Cup stadium and he said there was no ill-feeling lingering from what was a controversial end to Ballack's international career.
Low initially kept faith in Ballack after an injury in the 2010 FA Cup final ruled him out of the World Cup that year, but ultimately he never returned to add to his 98 caps.
"We have spoken with each other and of course we've also met up a few times, and there is no strife," said Low.
"We get on well. It is fantastic that he has got such a testimonial.
"He was a lead figure of German football."
The end of his time with the German national team was one of the low points in a career which lacked just one thing - major titles.
With Germany, Ballack was a runner-up at the 2002 World Cup and Euro 2008, while in club football he was on the losing side in two Champions League finals.
He did, however, win the Premier League with Chelsea, three FA Cups, four Bundesliga crowns and three DFB-Pokals.
"It was great, in spite of the difficult times," said Ballack.
"The lows were manageable. It was a very beautiful career."
