He stressed the difficulty of the challenge being 2-0 down against the unbeaten Lazio, but has confidence that his side can create the chances to win the game.
"Lazio haven't yet lost a game in the Europa League this season and that is our motivation," he told Stuttgart's official website. "We could become the first side to beat them.
"It's vitally important that we take a positive approach to the game and give our all. It's equally important to avoid conceding."
The match kicks off tonight at 8.05pm.
