There's literally a City fan calling Sanchez a mercenary for daring to accept United's offer over City's
He's chosen United because they offered more money. The likes of the BBC and Maks Cardenas both reported he'd prefer to move to City. They're as reliable as it gets in general and in terms of the Chile national team. The amount of City players I've seen called mercenaries on here, from Silva to Aguero, yet look at the umbrage as soon as it's suggested a player's gone to United with the primary motive being financial.
