There's lot of short term success managers who have that gift to change things for the better if the tools , players and finance are there.

There are occasions when big managers fail at very big clubs .

On the other side of the coin you have managers like Warnock who motivated those clubs with lesser skilled players .

You then have managers like Gerrard who get chucked into their first gig and off it goes.

For me it's about players wanting it and follow the new managers ways and tactics.
