The Junior Dragons battled to a 10-9 triumph over Georgia in greasy conditions to keep their semi-final hopes alive. Leon Brown crashed over after four minutes, but Wales could not build on their lead and were forced to hold on against the physical Eastern Europeans.
New Zealand await in the final Pool A clash after they suffered defeat to Ireland. And Strange wants to see Wales get back to their best as they attempt to topple the top-seeds.
He said: “The win was important but our performance was disappointing, we never got going. The boys will be down in the changing room because our play was frustrating to say the least. There isn’t a lot between New Zealand, Ireland and ourselves, but we will have to be a lot better than we were today. We know it will be a huge challenge on Wednesday but one we’re fully capable of meeting head-on.
“We want to play with width and intent but we overplayed in those conditions and Georgia played them well. We’ll take the win and move on to a big game on Wednesday. Georgia made it difficult, they were very committed and abrasive which we knew they would be. It was difficult to get any set-piece possession, it was a stop-start game. The boys have a lot of motivation for Wednesday night, it will be a huge challenge.”
