Neil Warnock rates his current role at Leeds as one of the toughest jobs he has had during his managerial career, but has no regrets about joining the club.
The 64-year-old has been in charge of 13 different clubs since taking up his first post at Gainsborough Trinity in 1980 and wants to be the first manager in English football to win promotion on eight occasions.
But the former Sheffield United and QPR boss has endured a tough time since arriving at Elland Road in February 2012, attempting to launch a promotion push with limited funds at a time when a protracted takeover threatened to scupper his plans.
Warnock, met with chants of 'it's time to go' after Leeds' defeat at Barnsley last week, said: "Over the years I've had one or two interesting jobs that haven't been easy. I'd put this in that category.
"I've had more takeovers than just about any other manager, three out of the last three clubs I've been at, and to keep the ship here sailing as it is isn't an easy job.
"There's a lot more involved than people realise and that's why I always say that all you can do is your best.
"But I think it needed someone with my experience to steady the waters here. I don't know how a younger manager would have coped with everything.
"All managers are expected to deliver. It goes with the territory. But all you can do is your best.
"That's what I set out to do this season. I can honestly say that it hasn't been one of my easiest jobs but it's one I wouldn't have resisted.
"It's a fabulous club and I still think the majority of supporters are behind me. You always get a few who aren't but that's only natural. They've had so many promises over the years and they're frustrated."
