If De Bruyne wanted to stay none of the last 3 months would have happened.Putting this in its barest financial terms, 10m€ a year earns KDB 93.5k€ net per week.
Even a salary of £200k per week offered by City would earn him 150k€ net per week.
Then we go onto the fact that footballing wise we are much more likely to win stuff AND our league is a lot higher profile.
I would hope that this should swing the matter (if indeed it needs to be swung).
