Whitehall insiders think Murray's advice could be particularly valuable if it is decided to build a new stadium away from Wembley at a site in need of regeneration.
Culture Secretary Chris Smith insists Wembley is still the front-runner for a new national stadium but his officials recognise the need to cover all possible eventualities.
The Stadium of Light, named after Benfica's world-famous ground in Lisbon, cost only £22.6million to build in contrast to the hundreds of millions which the Football Association insist will be necessary to construct a new England arena.
It has been ranked a FIFA Class A stadium and has already hosted an England 'friendly' international, against Belgium in 1999.
