What are they saying?
England manager Gareth Southgate:
"We are a team who are still improving" Southgate said. "We know where we are.
"We are having success because everybody is working so hard, everybody is working hard on the field.
"We are in this position because guys that are in the squad like (Gary) Cahill, (Phil) Jones, (Danny) Welbeck, (Nick) Pope, (Jack) Butland, (Danny) Rose, the older ones, have been exceptional in their mentality, their attitude to support the team, to train every day.
"Even though they've not had as much game-time as they would have liked, they are as much of a reason why we are where we are.
All you need to know about Croatia
"I think that collective has been key. All of the support staff, all of the players are really tight. We've built that and to get through the two games we've had this week needed all of that because we're not the finished article.
"We don't have renowned world-class players yet, but lots of good young players who are showing on a world stage that they're prepared to be brave with the ball, try to play the right way, have shown some mental resilience as well over the last few weeks.
"We know that in years to come, they are going to be stronger. But today was a huge opportunity for us and it was not something we wanted to miss out on."

England vs Croatia history and past results
Seven matches: England 4, Croatia 1, Draws 2
In Croatia, England willbe facing a side they know only too well. Luka Modric has only enhanced his already sky-high reputation as one of the world's best midfielders, while Ivans Rakitic and Perisic either side of him are both terrific foils for the Real Madrid maestro.
More than a classy midfield, however, England and Croatia carry history. It was that infamous November night at Wembley that etched Steve McClaren's umbrella into English footballing folklore. Scott Carson fumbled Niko Kranjcar's strike into his own net and England missed out on Euro 2008.
Arguably worse had come a year earlier when a Gary Neville back-pass inexplicably bobbled over Paul Robinson's right foot. Those two defeats - however harrowing - are the only two. In fact, England lead have won the most recent pair of fixtures by a combined score of 9-2. Theo Walcott scored a memorable hat-trick in Zagreb a decade ago.
