Coventry City 6 Derby County 1
Micky Adams has had to deal with more than his fair share of dressing room discord during his managerial career but he must have thought he was in for an evening of sweetness and light after this emphatic victory.
But footballers are curious creatures and there was clearly some bad blood between strikers Stern John and Gary McSheffrey.
Both scored twice to make it seven games unbeaten at the Ricoh Arena but the former Birmingham City man was not happy.
He had scored twice - after being wonderfully set up by Michael Doyle and Dele Adebola - and thought his hat-trick was within easy reach when McSheffrey was fouled in the area by Michael Johnson.
McSheffrey, the regular penalty taker, had different ideas and he hung on to the ball to slot his 12th goal of the season. Not that John witnessed the moment - he had already turned his back and was sulkily walking back to the halfway line.
The debate carried on into the dressing room and John was clearly unimpressed.
Coventry unhappy after a 6-1 victory? Adams will have been delighted.
Whoever one thinks should have stepped up to the mark and there are arguments on both sides, it was good to see two Coventry players so keen to take the responsibility.
Although the mood was obvious, it did not in the least sour the day for the Sky Blues followers who are now seeing the Ricoh turned into something of a haven from the other travails of the City season.
Not that any of them could have seen a 6-1 scoreline coming after such an average first-half performance.
Adams gave Dennis Wise his debut and it took the combative little midfielder just eight seconds to leave his mark on the game and the shin of Seth Johnson. Later in the game the challenge would have earned the 39-year-old a caution but he got away with it and continued to yield a positive influence.
And there was certainly plenty of encouraging to do when, after just 64 seconds, Ady Williams, who had a very shaky first 45 minutes, put through his own net as he tried to clear from Paul Peschisolido.
Coventry did recover quickly and Michael Doyle, who is improving match-by-match after a wretched start to the season, played a superb pass to allow John to net his first.
Crucially Coventry started the second half very strongly and had won the game inside 15 minutes.
Dele Adebola set up John for his second, Wise added a third goal and then Adebola headed home to make certain of the points.
Derby boss Phil Brown, who bizarrely put the defeat down to poor refereeing, should be alarmed at the way his side capitulated.
McSheffrey then added his two to set up the entertaining, if rather puerile, sideshow.
Skipper Doyle came down firmly on the side of McSheffrey: "Stern is upset about it but Gary is the penalty taker and I would rather see him take it.
"He missed his last penalty but he was man enough to step up and take this one. I backed him 100 per cent. Stern has got two goals but you have to pick yourself up and you can't mope about it.
"Stern was disappointed in the dressing room but he played great. There was not a lot we could say to Stern but Gary is the penalty taker.
"I said to Gary 'would Michael Owen or Alan Shearer tell someone else to take it' - I don't think so.'"
