Former England skipper Terry Butcher has agreed to become part of Scotland boss George Burley's backroom staff.Burley asked his former Ipswich team-mate Butcher and Celtic defender Steven Pressley to assist him after he was appointed last week. An SFA spokesman told PA Sport: 'Terry has agreed in principle to start working with George.' The SFA now hope to iron out a deal for Butcher to become a part-time assistant to Burley before the squad gathers for a training camp on Sunday. Pressley has yet to agree a deal to join the backroom team of Burley, his former Hearts manager, but the Scotland defender is expected to follow suit. Pressley was omitted from a 27-man squad that Burley named earlier for a three-day gathering at Loch Lomond. There were no new caps in the party and Burley signalled his intention to stick with the players that served Walter Smith and Alex McLeish so well by including 37-year-old Rangers defender David Weir. Burnley full-back Graham Alexander also retains his place while fringe players such as Dundee United skipper Barry Robson and Derby pair Stephen Pearson and Gary Teale are included. Ipswich goalkeeper Neil Alexander and Norwich's David Marshall join Craig Gordon and Allan McGregor.
