The 26-year old winger has made seven appearances for the Scottish national team since making his debut in September 2013, and his goal against Germany was his second in the blue of the Tartan Army.
Well known in the Championship for his pace and attacking intent, the wing-back-cum-forward - who was eligible for four nations before choosing the land of his birth - the Scotsman’s final ball has always been a let down, but he overcame that to run through the Germany defence and finish past Manuel Neuer - commonly regarded as the best goalkeeper in world football.
Despite Germany going on to win 2-1, with Anya’s goal coming in the middle of a Thomas Muller double, the Hornet revealed his delight at his goalscoring in an interview given to the official Watford website.
In the wake of the defeat, Anya said: “It was crazy. I’m not sure it’s going to get any better than that! To score a goal against the world champions is something special and it’ll take some beating,” beamed Anya after the Euro 2016 qualifier.
“It’s definitely the highlight – when I saw the ball hit the back of the net it was the best emotion I’ve ever felt in football.
“Steven Fletcher put me in and I just thought ‘run as quick as you can’. Neuer looked massive but I was just thinking about trying to put it in the bottom corner. It’s something I practice quite a lot and luckily it went in.
“Neuer tried to put me off, he came and then stopped and then came again when I got into the box, but I thought I was close enough to try and side-foot it in. Fortunately I managed to lift it a bit and it went into the bottom corner.”
Having arrived at Vicarage Road after unsuccessful spells with non-league outfits, then-head coach Gianfranco Zola gave him his chance to impress, and is commonly regarded as being the man who improved Anya to the point of national appearances.
Having struggled to nail down a guaranteed first-team role this season with the Hornets, impressing as he did against the world champions will give new boss Oscar Garcia much to think about in preparation for Saturday’s fixture with Charlton Athletic.
