Michael Ballack is struggling to understand the motives behind Robinho's decision to join Manchester City.
The Brazil international opted for a lucrative transfer deadline day switch to Eastlands over a move to Premier League powerhouses Chelsea.
It had appeared inevitable the talented playmaker would arrive at Stamford Bridge this summer once he made the announcement he was seeking a switch away from Real Madrid.
However, with City revelling in the financial backing of the Abu Dhabi United Group they were able to hijack the move with a record-breaking £32.5million raid.
Ballack feels Robinho was ultimately swayed by money, as Chelsea represented the better option for anyone with ambitions of challenging for honours.
"It is up to each player what they do, but if I were him, I would not have gone to Manchester City," the German midfielder told Tagesspiegel am Sonntag.
"A transfer from Real Madrid to Manchester City is hard to justify with sporting reasons."
Ballack feels his own decision to move to Stamford Bridge provides an ideal example of how a player should look for continued progression throughout their career.
"I certainly do have a good contract here, but my career progressed," he added.
"I did not go from Chemnitz to Bremen, although I had an offer from them, but I went to Kaiserslautern, who had just been promoted because I saw more chances for me to play there.
"Then I went to Leverkusen and not to Bayern, where I also had a contract awaiting my signature.
"Then in 2002, I went to Bayern and not Real Madrid, although I had a lucrative offer from them. And now I am at Chelsea, an absolutely huge club in the best league in the world at the moment.
"I feel very happy with Chelsea and in the city of London and I would happily end my career here."
Ballack is also hoping to play his part in helping the Blues write an exciting chapter in the club's history.
"This is a club which is growing," he said.
"Just look at our youth system and what is happening there. This club is creating a new tradition and it will enjoy lots of success.
"In 20 years' time I could say that I was at Chelsea and it is there that I ended my career."
