Ballack was asked why he chose Chelsea over Manchester United, he replied:
"Yes, Manchester United wanted me, and it's a good question. They came before Chelsea, but I didn't really have discussions with Sir Alex Ferguson. At this time United were not really good in the Champions League, they had gone out in the first round that year.
"But Chelsea was growing really quickly, so I wanted to be a part of this. I saw we could reach something really, really big in the next few years."
