Having qualified for their first major tournament in 58 years, Wales are seemingly determined to make their on mark on this summer’s competition in France, which sees them contest a group containing England, Russia and Slovakia.
But after watching the Foxes upset the odds to bring themselves to the brink of the Premier League title, the Swansea captain insists that anything is possible.
According to the Daily Star, the defender said: “When you see sides like Leicester doing well and you think back to Greece winning the Euros in 2004, it does give you confidence.
“We have seen it before. If you get a bit of momentum, remain tight as a squad and work for each other you can be successful, hopefully that can take us far into the tournament.”
Chris Coleman’s team continue their preparations for this summer’s tournament with a friendly with Ukraine in Kiev on Monday.
With star duo Gareth Bale and Aaron Ramsey both set to miss the trip, Williams admits it will be a tough test for his team, but insists it will help players to further strengthen their claim for a place in the Euro 2016 squad.
“We want it to be risky and we want it to be edgy. That is where you learn more about players,” he said.
“I prefer it like this. We are in their backyard in a tough atmosphere and we have to show we can cope.”
