Gordon Strachan has announced his Scotland squad to face Lithuania and Malta in the World Cup qualifying double header next month.

Millwall keeper Jordan Archer receives his first call up to the Scotland squad after helping the English side to promotion to the Championship last season, at the expense of Hearts keeper Jack Hamilton.

There are also recalls for Steven Whittaker - now at Hibernian - Newcastle United duo Matt Ritchie and Grant Hanley, and West Brom's Matt Phillips.

In-form Celtic midfielder Callum McGregor has been left out of the setup once again, despite helping the Scottish champions to complete a domestic clean sweep last season and on the brink of reaching the group stages of the Champions League for the second successive year.

Celtic have six players in Strachan's squad, while there are no representatives from Aberdeen or Rangers.

Question marks are hanging over some of Strachan's call-ups including Grant Hanley, who has not played since April, yet he is preferred to the likes of Mark Reynolds of Aberdeen who has played consistently for the Dons throughout last season and this one also. Since returning to the English Premier League, Hanley has not featured in the match day squads for Rafa Benitez's side.

Scotland are currently fourth in Group F trailing league leaders England by six points. They will face Lithuania on 1st September in Vilnius and then Malta three days later at Hampden Park.
