The Three Lions face Switzerland in a Euro 2012 qualifier at Wembley on Saturday.
Inler said: “We can pull off a major coup at Wembley. We’ll approach the game with a fresh tactical approach.
“This is a new start for Switerland. We have to beat England in order to stay in the hunt – but they are not unbeatable.
“If we play with the commitment we showed against Spain during last summer’s World Cup finals, when we won 1-0, then anything is possible.”
