Young Scots chasing win in Victory Shield
The Welsh, who tied with England in the tournament in 2005, are also out to ensure they get the three points after their 4-0 demolition of the English in their first game.
Mathie said: "This tournament is decided on points only and therefore a win for either side tonight means that they will at least get a share. Wales were four-nil up (against England] by half-time and they will be extremely buoyant after that, so we are well warned about how difficult this game will be. We won down there 1-0 last season with a flash of brilliance from Islam Feruz, but it was another very tight game."

Young Celtic striker James Kirwan, who scored in the opening win over Northern Ireland, is a doubt with a hamstring injury
