Norwich piled more pressure on Derby boss John Eustace after thrashing the Championship strugglers 4-0 at Pride Park.

On his 47th birthday, Eustace saw his side ripped apart by the pace and movement of the Canaries, who scored three times before the break.

Anthony Musaba, Paris Maghoma and Darlin Yongwa put Norwich in complete control before substitute Jovon Makama wrapped up a third straight win for the visitors and condemned Derby to a fourth defeat in five games.

Derby have won only once this season and Friday night's home game with Bolton now looks like a huge one for Eustace.

They went into the game as only one of two teams without a home win in the Championship and they fell behind in the eighth minute. Jack Stacey crossed from the right and although Yongwa's header was saved, Musaba slammed the rebound into the roof of the net.

Musaba had a great chance to score his second in the 15th minute when Andre Brooks played him in but his low shot struck the legs of goalkeeper Jacob Widell Zetterstrom.

Norwich looked like scoring every time they came forward and after Zetterstrom made a reflex save to deny Mathias Kvistgaarden, Maghoma made it two with a curling effort from the edge of the box in the 27th minute.

Boos rang out from the home fans and only the woodwork denied Norwich a third when Stacey's shot hit the inside of a post and was cleared off the line by Alex Mowatt.

It got even worse for Derby just before half-time when they were torn apart again and after Brooks fired the ball in from the right, Yongwa made no mistake from 12 yards.

The half-time whistle was met with another chorus of disapproval from the home fans and it was no surprise when Derby made three substitutions for the second half.

Derby at least had an effort on target with a Carlton Morris header forcing Daniel Grimshaw into a diving save and there was certainly more urgency about their play but Norwich were not finished.

Makama came to the party in the 66th minute with a rasping drive from the edge of the area which Zetterstrom could not keep out.

That was the signal for Derby fans to head for the exits and some of those who stayed joined in when Norwich fans taunted Eustace with chants of "sacked in the morning".

It was certainly a miserable night for Eustace and Derby, who even at this early stage look like a team fighting relegation.
