A penalty from David Bexkham and a first half header gave England a two nil cushion before Croatia struck back to make the score 2-1.
However, former Ipswich here Dyer was to help seal the win for England by setting Chelsea's Frank Lampard up for his first international goal, and what a screamer it was, flying into the keepers right hand corner of the net from around 25 yards at 75MPH.
Dyer made an instant impact after coming on, and it was obvious for all to see that playing for his Country at his home ground meant a lot to him. Speaking of his peformance, Dyer said : "I was really pleased with my performance, in a position I really like, which makes a change for England.
"It all went to plan but a goal would have topped it off. But I'm still happy because we got a good result, I played well and I got a good reception.
"Sven had a quiet word with me after the game and said it could be my best position so hopefully that little cameo keeps me in good stead with him."
Dyer will also have felt he was unlucky to have a goal ruled out himself, after breaking free of the Croatian defence before slotting the ball round the keeper, only for have the goal ruled offside. A decision which was later proven incorrect by TV replays.
Speaking of the game, Kieron told the East Anglian Daily Times he felt the goal should have stood : "I knew I was onside and it should have counted.
"It would have capped a fantastic night for me. The reception I got was amazing. Even when I was warming up they were chanting my name, it was truly brilliant.
"Without those fans and this club I would not be the player I am today and I thank them for that.
"I never dreamt I would come back here playing for my country and I'm one of those who is glad Wembley is getting done up at the moment because that gives a lot of players the chance to play for England in their home town.
"Even when they said about an England roadshow I never thought in a million years I would be back here. But Ipswich has a fantastic stadium and it does not do itself justice in the First Division."
