So Spain's era of dominance in world football is completely over now. The national team could not get out of their World Cup group in Brazil in the summer, and now their Under-21 team have failed to qualify for the European Championship in 2015.

They drew the first leg 0-0 in Serbia, but slumped to a 2-1 home defeat in the second leg.

The Spanish line-up included Liverpool full-back Javier Manquillo, Stoke midfielder Marc Muniesa, winger Gerard Deulofeu, who enjoyed a successful loan spell at Everton last year, and Real Madrid attacking midfielder Isco (pictured).

Elsewhere, Portugal won a thrilling second leg 5-4 to defeat Netherlands 7-4 on aggregate. Germany beat Ukraine 3-0 in the second leg, to seal a convincing 5-0 aggregate success. Iceland and Denmark are currently goalless, and could be heading into extra-time.

Bflo Celtic:, external After Robertson's fantastic performance on Saturday, I'm surprised he's not starting. I don't rate Whittaker highly, either.

Scotland make two changes to the side that started against Georgia. Defender Gordon Greer replaces the injured Grant Hanley, while full-back Steven Whittaker comes in for Andrew Robertson in a tactical change by Gordon Strachan.

Ikechi Anya is fit to face the Poles despite being rated doubtful.

Scotland starting XI: Marshall, Hutton, R Martin, Greer, Whittaker, Brown, Morrison, Maloney, Naismith, Anya, S Fletcher.

Two changes for world champions Germany from Saturday's shock 2-0 defeat in Poland. Chelsea forward Andre Schurrle and Borussia Monchengladbach midfielder Christoph Kramer are both injured and are replaced by Schalke's Julian Draxler and Borussia Dortmund's Matthias Ginter.

Germany starting XI: Neuer, Rudiger, Hummels, Boateng, Durm, Ginter, Kroos, Bellarabi, Gotze, Draxler, Muller.

As expected, Stoke striker Jon Walters returns to the Republic of Ireland side. Martin O'Neill makes two other changes from the thumping 7-0 win against Gibraltar, midfielders Glenn Whelan and Stephen Quinn given the nod.

Republic of Ireland starting XI: Forde, Meyler, O'Shea, Wilson, Ward, McGeady, Whelan, Quinn, McClean, Keane, Walters.

Charles Rigden:, external Harry Kane looks like he could give Rickie Lambert a run for his money in that 'Big Man' role that England have in their squad.

And that's it. Job well done. England qualify for the European Under-21 Championship in Czech Republic. Jack Butland's early save to deny Croatia taking a third-minute lead proved crucial.

Liam Moore's close-range volley put Gareth Southgate's side ahead, Marko Livaja equalised just before half-time, but England looked comfortable after the break.

Will Hughes scored the second goal of the day for the visitors to ease any nerves and England can now prepare to take on the continent's best youngsters next year.

Peter Collins: Re Greg (71 min). While Hughes does have a big future, it would be nice to see him develop at Derby. He won't get near the Man Utd team at the moment.

England Under-21 and Burnley defender Nathaniel Chalobah:, external Yes Will, what a finish lad. Almost there boys.

Alistair Bruce Ball thinks it is all over and what Hughes's goal - his second for England U21s - has done is mean there cannot be extra-time. If Croatia score two more, then England would still progress on away goals. Croatia need three goals and have got 15 minutes to get them.

Not impossible, but very tricky.

"It has been an even second half, both teams have had chances, but that goal is vital. It is pretty safe to say that England Under-21s will be qualifying for their fifth successive European Championships."

Well, Greg may want him at Old Trafford, but Will Hughes's price tag may have just gone up a notch.

The Derby midfielder, who has been excellent tonight, twists and turns on the edge of the penalty area to create some space for a shot and he arrows an effort past Dominik Livakovic and into the bottom corner.

Greg, Sale: Will Hughes best player on pitch. Would love him at Manchester United, big future ahead.

Twenty minutes to go. England are inching their way closer to Euro 2015. The players are working hard, and stifling Croatia's attacking flair. But, remember, all it takes is one goal from Croatia and we will have extra-time. Two goals for the hosts and England are out.

How are your nerves holding up?

German FA:, external Here's a look inside the tunnel at the Veltins Arena - 90 minutes until kick-off!

Looks a bit spooky if you ask me. Can Republic of Ireland shock the world champions later?

Rob, Manchester: Re Matt, 47 mins, I know we're not the dominant force we once were but surely Manchester United are still classed as a big club, and have Shaw, Keane and Blackett who are all England U21 players.
