The out-of-favor Bayern Munich winger would consider moving on from the European champions in search of regular first-team minutes.
The Switzerland international has found regular first-team minutes hard to come by since joining the European champions in 2012 and is keen to seek out opportunities elsewhere.
His brother and representative, Erdin, told Swiss newspaper Blick: "Xherdan is 22. At that age he has to play regularly, which is not the case at the moment. We will wait till the summer. If then clubs like Liverpool, Manchester United or Inter will ask, we will surely listen."
Shaqiri faces tough competition from the likes of Arjen Robben, Franck Ribery, Mario Gotze and Thomas Muller to break into Pep Guardiola's starting XI.
