Borussia Dortmund midfielder Mario Gotze has warned title rivals Bayern Munich that money does not always equate to success on the pitch.
The 19-year old, who burst onto the scene last season with six goals and 11 assists, was reacting to a summer of big spending in Bavaria, which has seen Manuel Neuer, Rafinha and Jerome Boateng move to the Allianz Arena among others.
"Chelsea have also tried often (to buy success). When you invest a lot, you are not automatically a success. Bayern have a superb team but we showed last season that we can also play football," Gotze told Bild.
Gotze is looking forward to the upcoming season, which will see Champions League football return to the Signal Iduna Park, a prospect the youngster is relishing.
"I am really looking forward to the Champions League. My childhood dream was always to play just once in the Camp Nou.
"It is fun to watch teams such as Barcelona or Arsenal play."
Already a firm favourite with the Dortmund faithful, Gotze revealed that he keeps his feet on the ground by living with his parents.
"I see no reason to have my own place. There is nothing better than living at home. I have my parents here, my brother - and I don't have to everything myself."
