Bayern Munich midfielder Xherdan Shaqiri's agent is unsure whether his client will be able to secure a January transfer despite Liverpool's interest in his services.

The Swiss international has grown increasingly frustrated with his lack of playing time under Pep Guardiola amid suggestions the former Barcelona coach doesn't believe the 23-year-old is capable of adjusting to his system.

The winger suffered similar problems last season and appeared poised to leave the club, only for Bayern to block Liverpool's attempts to sign him.

His agent, Ulisse Savini, now claims Shaqiri will find himself in a "difficult situation" during the January transfer window and doubts Bayern will be willing to offload him half way through the season.

"I doubt he can switch in January," Savini told Italian radio station Centro Suono, Football Italia report. "He has played in the Champions League and cannot be used there (Shaqiri will be cup tied if he leaves Bayern for another club participating in the competition).

"This complicates the agreement, since it would be for a lot of money. And I doubt that Bayern can find a replacement of his level. "

Liverpool were reportedly keen to sign Shaqiri during last season's January transfer window after they failed in their bids to sign Mohamed Salah and Yevhen Konoplyanka.

The club were understood to have been one of a handful of clubs keen to sign him again in the summer only for Bayern to tell him he remained part of the plans at the Allianz Arena.

"It was known that I wanted to do something in the summer," Shaqiri recently told the Swiss press. "After the World Cup I felt that it would be better for me to try something new. Then Bayern decided I should stay. In that case, you cannot do much as a player. But I feel very good at Munich, too."
