The 65-year-old has vowed to adopt the same tactics that have served him so well during his Switzerland tenure and is hopeful of springing a surprise.
"We will remain true to our philosophy," he told the Swiss Football Association's official website.
"That is, we want to build on our good organisation and compactness, accept duels and quickly switch from winning the ball in defence to attack.
"I am convinced that we have opportunities. We are the clear outsiders but we have nothing to lose and much to gain.
"We can make history on Tuesday. Each player has the chance of his personal history being accompanied by a large chapter. In one game, anything is possible."
