The left-back was sent off on his Derby County debut.
In the winter Leeds United went on something of a clearout. The likes of David Norris, Noel Hunt and Jason Pearce were all sent on their way. They also let former England international Stephen Warnock leave the club.
The left-back joined promotion chasing Derby County on an 18-month deal.
But things did not start well for Warnock at the iPro Stadium. He was sent off on his debut against Reading.
Since then he has been out of contention, playing just once until starting Monday’s 2-0 win at Wigan Athletic, and he has admitted it was his own fault he was out of the team. He is quoted in the Burton Mail as stating:
"It was one of those where you get a bit excited because you want to do so well and I maybe rushed into a couple of things I probably shouldn't have.
"Since then, I've had to bide my time But that's the way football goes and you've got to try to bounce back. It is tough being out of the side but I've only got myself to blame for that."
Derby have had to make changes recently after a run of form which saw them drop desperately close to falling out of the play-off contention.
But the win on Monday ensured they remain in the top six currently, although they have Brentford and Ipswich Town breathing down their necks in seventh and eighth respectively.
But Warnock’s defensive nous could prove vital in the final five games of the season, as The Rams look to push on for promotion to the Premier League.
