David Alaba reportedly feels undervalued by Bayern Munich as he considers the next step of his career.
While the long-serving defender ultimately remained with the Champions League winners during the summer transfer window, he now has less than a year remaining on his deal.
Bayern are eager to retain the services of the Austria international, who has been at the Allianz Arena since 2011.
However, Bild claims that the 28-year-old and his representatives have been left unhappy with Bayern's recent contract offers.
Although Alaba is said to have been offered a significant pay rise, the report suggests that the versatile player wishes to earn a salary closer to the likes of Thomas Muller and Robert Lewandowski.
Liverpool are allegedly monitoring the situation as they consider potential replacements for the injured Virgil van Dijk.
