Warnock turns 70 in December, he defied all the odds to get Cardiff up to the Premier League last season and now they are stacked against him to keep them up.
He told the Mirror: “It's my hardest challenge by an absolute mile. Biggest ever. I always knew it would be. I knew before the end of the season I knew what my budget would be, what I could spend so I knew it would be a minor miracle in that respect.
“When I took over, who would have said 18 months ago that we'd be in the Premier League, turning people away because we're sold out three or four days before a game? People would say I was in cloud cuckoo land!
“The place is just gripped by it. It's great in a time where there's a lot of depressing, negativity around the world, I think it's great that in Cardiff we've got something to look forward to each week.
“Even in the supermarket the other night, I must have had ten selfies with me — kids with their mothers. Mind you, I think it was the kids taking the pictures of the mothers with me!"
