I'm not that high on him but he rarely plays his best position imo
Isn't that a fairly good reason for not wanting to stay or trusting Rodgers, ultimately his break out season was playing wide, sometimes centrally but behind a striker. This season Rodgers has striking options but has frequently, rather stupidly, decided to play him as the main striker which hasn't worked out the majority of the time he's done it.
Either way, players move on, or not, he's supposedly turned down one contract offer, people are banging on about loyalty and bad advice. Loyalty is something generally perceived rather than real. Gerrard was happy to use a supposed move to Chelsea to get a pay rise, had liverpool not upped their offer he'd probably have gone. Sterling will at this stage either likely move on and get something that he's been promised already, IE more than 100k a week, or Liverpool could easily offer him more at which point he'll agree.
As for the idea that losing out on 35k a week for two years would be hard to make back. If he went the whole hog and waited to leave on a free transfer in 2 years he could easily make back that frankly piddling 4mil as a signing bonus. If say City or whoever would otherwise have to pay 20-40mil for him, waiting 2 years and giving him 10mil signing bonus as an incentive to see out his contract makes financial sense for all involved.
The only way people can say he's been badly advised is if he ends up making less than 100k a week on his next contract, where ever it happens to be.
Players like Rodwell, Sinclair, aside from the fact neither were anywhere near as good as Sterling has already shown and neither had the potential, they were both massively over rated and both have made millions more than they could have playing anywhere else had they not moved to City. Neither player was badly advised, neither player is truly top notch, neither would have got that money elsewhere, both are now at clubs maybe at the level they deserve anyway.... they could have gone to their current clubs directly and been millions worse off. anyone who thinks either player has been badly advised is delusional.
