Xherdan Shaqiri says he will leave Bayern Munich this summer if there is no prospect of him playing more frequently next season.
The Switzerland international told the newspaper 20 Minuten that he was not happy with the limited opportunities he got under Pep Guardiola last season.
The 22-year-old appeared just 17 times in the Bundesliga, although injury also prevented him from playing more frequently.
"I'm not going to go through another year like this," he said. "If not much changes, then I will have to change something."
Liverpool and a host of clubs in Italy are reportedly tracking the midfielder, who scored six goals in the Bundesliga last term, although he has a contract with Bayern until 2016.
"We'll just have to see what happens," he added. "I'd only be interested in a club who could challenge for silverware."
Shaqiri joined Bayern two years ago from Basle, and he feels he has become a better player, particularly in his first year under Jupp Heynckes.
"I've gained more experience and things have improved sportingly too," he said. "I've got better.
"I felt Heynckes had more faith in me, but that's maybe also because Guardiola talks with us less."
