The Germany international has returned to training after winning the World Cup over the summer and is keen to go one better than last season by lifting a trophy
Jose Mourinho has signed Cesc Fabregas, Diego Costa and Filipe Luis this summer, as well as bringing back club legend Didier Drogba to Stamford Bridge.
The Londoners finished third in the Premier League in last season but Schurrle, who played a key role as Germany won the World Cup in the summer, says the team are capable of winning silverware this year if they work hard.

"We have the squad, we have the players and now we just need to work hard."
Schurrle added of the new recruits: "They're all world-class players. Drogba's back with his club and Fabregas is one of the best players in the world.
"We played against Filipe Luis last season when he was with Atletico [Madrid] and he did very well. I saw Diego Costa's goal against Olimpija Lubljana and it was a great finish so I'm looking forward to playing with all of them, they all have great quality.
"I've had a short break after a hard year but I want to work, I want to get fit," the forward continued. "It will take a bit of time to get going but we have great staff here, a great team and hopefully I'll be fit by the time the season starts."
