Stiliyan Petrov and Ashley Young could come up against each other at Wembley tonight when the Villa skipper leads Bulgaria out to take on England in a European Championship qualifier.

The road to Euro 2012 kicks off this evening with a number of claret and blues stars in action for their respective nations.

Petrov is set to embark on his final international tournament qualification campaign, with Bulgaria getting their Group G campaign underway against the Three Lions.

With England in transition after a disappointing World Cup, Young will be hoping to add to his eight caps and stake his claim to be a regular in Fabio Capello's future plans.

In the same group, James Collins looks set to line up for Wales against Montenegro as John Toshack's team aim for a winning start to qualification.

The Welsh side face a tough away assignment at the City Stadium in Podgorica.

Collins brings crucial experience to the young Wales team and is likely to line up in central defence for his 35th cap.

Richard Dunne has been named in Republic of Ireland's starting XI to take on Armenia in Yerevan.

The defensive colossus takes his place alongside Preston's Sean St Ledger, John O'Shea of Manchester United and Hull City's Kevin Kilbane in Ireland's back four.

Giovanni Trapattoni's team will feel they have a good chance of competing in Group B, which also includes Russia, Slovakia, FYR Macedonia, and Andorra.

John Carew is set to sit out Norway's Group H clash against rivals Iceland, after sustaining a knee injury.

Nathan Delfouneso and Marc Albrighton are in Portugal for England under-21s' crunch Euro 2011 clash.

The under-21s still have hopes of reaching next summer's European Championship finals in Denmark but they must beat Portugal in the Group H clash in Barcelos.

England currently trail leaders Greece by five points, but a victory over Portugal could give them a fighting chance going into Tuesday's final qualifier against Lithuania in Colchester.

Barry Bannan's Scotland trail leaders by a point in Euro 2011 qualification Group I, ahead of tonight's crunch meeting between the two sides at Pittodrie, Aberdeen.

Moustapha Salifou's Togo are also in action this weekend. They travel to Botswana on Saturday in an Africa Cup of Nations qualifier.
