Well said.
Any player moving would be stupid not to try and make it as financially rewarding as possible(and that is one of the reasons they employ agents), but it's rarely the actual reason they move.
Why are you making it so black and white. It's a circular argument to be honest
But Money is clearly a huge part of the equation. More than 50% especially moving to a club with limited historical pedigree like City. Yes now moving to a city comes with a chance of winning things but Walker wouldn't be interested if they were offering the same wages as we are joining a team in the past he has previously slated on Twitter for being new money and their past unsuccessful history
Also at the start of the City project the likes of Robinho, tevez, yaya clearly moved a big part due to the money and that's created the momentum we have today...today yes maybe you can it both but if City were offering standard wages their attraction vs other clubs in the league would be limited
Same way if China does keep buying those just interested in the money in ten years they may (still unlikely I would think though) have a league good enough to attract those motivated by both money and prestige
