The former Wales international is undoubtedly a high quality coach, but it was not working for him as a manager.
After 11 League games, only eight points collected and with the club precariously in the relegation zone – Trollope was sacked and the ultimate Championship manager arrived to unusually united acclaim from supporters.
Warnock has worked his magic by transforming the team and galvanising the fan base.
When he meets owner Vincent Tan this month, Warnock will have a strong hand to gain the funds he feels he needs to launch a promotion challenge next season.
The Cardiff manager believes he already has a solid base upon which to build next season.
Keeping Gabon defender Bruno Ecoule Manga would be a significant boost. The signs are good after it initially looked as if the cultured centre back might seek pastures new.
But negotiations seem to still be hanging in the balance.
Defensive resources appear to be good at Cardiff, particularly with Sol Bamba excelling since his arrival with Warnock.
Of course, the goalkeeping spot has to be a priority, as Scotland’s Allan McGregor and youngster Ben Amos return to their parent clubs after loans.
Warnock’s unsuccessful January pursuit of Aberdeen’s Jonny Hayes suggests the Cardiff manager is looking to boost his options on the flanks, which may see the attempted offloading of Craig Noone and perhaps even Anthony Pilkington.
There is an industrious look to the midfield – when isn’t there with a Warnock side? – with Joe Ralls and player-of-the-season Arron Gunnarsson, though more pace is required.
