Dm what about the club where he started? Didn't spend bucket loads there. With the statements given out it's quite clear the Arab owners and Sven are here for the long haul. There is no quick fix. He also only lost a handful of games for England and got city to Europe. All be it by a bit of luck.
Sweden, meh, to be completely honest, being a manager in say, Scotland, of either Celtic or Rangers, even if you're cack you'll start off with a team that will win it in a few years at the most. Same as being manager of Porto isn't a particularly hard task to win the league(till they sold every decent player in one go). Take I dunno, Hib's to the scottish title and you're talking, take the clear leaders and keep leading, not that impressive.
I think he spent something like 13 years in Serie A being fairly crap before he won a title, and spent something along the lines of £240mil, a DECADE ago, to do so. Since winning with Lazio he's done pretty much nothing, England might have won a lot under him, but its not hard to beat the San Marino's of the world, we played crap footie throughout and were no where near an improved or better team.
City were a decent team lacking a couple strikers with a much improved defence, they literally had no strikers, he bought a bunch of them, all overpriced, all basically now gone as their form went to crap. Ireland and the defence got City into Europe.
He buys success or started with it, he's yet to take a good team and make them great but he's often taken a team and without cash available made them worse.
The very clear problem is he can only get short term success. Elano and the likes on huge wages coming in for big fee's are confident as can be, as the season went on all his new buys turned to crap and his man management/motivational skills were non existant. Same for England, couldn't get them going nor did he pick the right squads, just whoevers popular, tactics were awful.
Considering he doesn't know lower league players, can't get tactics or motivation right, can't bring in huge names to just buy success, I don't know what he'll do. Of course he can just get them to buy players from a league or two higher on big wages and I'm sure they'll do ok with that, for a while.
