Kenny and Warnock seem to work well together. This is the fourth time that Kenny will be managed by Warnock as Warnock was also the boss at Bury, Sheffield United, QPR and Leeds.
37-year-old Kenny has joined Rotherham to give them support during the end of the league. Warnock told Rotherham club's official website, "Young Alex Cairns is a good keeper but I think that at this level you need a bit of experience at what is a critical time of the season."
