I don't see the problem in congratulating the opposition, especially when they have played very well and the result has been so one-sided. If it were Palace, of course, that would be different.
A big well done to Derby. You were great to watch and well deserved your victories and I'm confident you'll make the Premiership this time round. Good luck for next year. Sorry we couldn't have made more of a game of the play-off legs but I would imagine you're not too bothered about that.
