The Edinburgh Gunners wing has earned the tag 'supersub' after a number of crucial displays following his arrival as a replacement.

The 24-year-old began the season as third-choice wing at Edinburgh - behind fellow Scot Chris Paterson and Argentina international Francisco Leonelli.

Webster slotted in perfectly after Marcus di Rollo suffered a hamstring injury in the 29th minute of the RBS 6 Nations Championship win over France on Sunday.

Webster will remain on the bench for the trip to Wales on Sunday after Ben MacDougall was drafted in to replace Di Rollo at centre.

But the former Northampton Saints man insists he will be happy to play anywhere - just to enjoy occasions such as the 20-16 triumph over the French at Murrayfield.

Webster said: ''If we are winning, then just to be a part of it is quite special, so keeping in the 22 is the most important thing for me at the moment.

''To be honest, I do like the idea that people think of me as a kind of player who can change the course of games.

''That is quite a cool thing, but, at the same time, I would like people to look at me as someone who can make a big impact right from the start of the game.

''If it meant I could be involved in another win like last Sunday's against France, then I don't mind being on the bench, the wing, at centre or even at hooker.

''I would play anywhere to be involved in a day like that again.''

Webster also replaced Di Rollo in the fine Scotland display against all-conquering New Zealand in November and went on to score a try.

But the Edinburgh man understands why Scotland head coach Frank Hadden has handed MacDougall the centre berth for the game at the Millennium Stadium.

Webster said: ''The coaches must feel I can do a job at centre or they wouldn't have me on the bench because it wouldn't be ideal if I could only cover the wing.

''But, obviously, covering that position and starting there are two quite different propositions.

''I really don't know how serious a contender I am for a place in the centre, but, first and foremost, I would like to think I am a serious contender for starting on the wing.

''I certainly still see myself as a genuine winger, who can play elsewhere if needed, and, to be honest, I'm sure the coaches do as well.''
