West Ham have gelled surprisingly well under Slaven Bilic, racking up several impressive wins so far this season.
Sometimes, gambles pay off

Next season West Ham move to the Olympic Stadium, and in such shiny new surroundings, Premier League football is a must or else a lot of people would look very silly indeed. While one cannot necessarily plan these things out precisely, there was a definite sense that West Ham's relationship with Allardyce had run its course. Replacing the sure thing with Slaven Bilic was a pretty significant risk for the Hammers, but it's one that appears to be paying off very nicely.
With a combination of shrewd signings, such as Dimitri Payet and Manuel Lanzini, and a different managerial approach, West Ham sit in the Champions League places under Bilic after 10 games, playing exciting football and with a stack of high-profile scalps on their record. It's still early, but David Gold, David Sullivan and Karren Brady putting their faith in Bilic looks like a risk well taken.
