Winger Jeremain Lens admits he is unhappy with a lack of first-team football at Sunderland and could leave the club in January.
Holland international Lens only joined Sunderland in July in a £8million move from Dynamo Kyiv and has featured 12 times in the Premier League this season, scoring twice.
However, the 28-year-old has not started since the 3-0 victory over North East rivals Newcastle in October, and is growing increasingly frustrated with life under Sam Allardyce.
“It’s definitely annoying. I am not playing and I did not come to the Premier League to sit on the bench,” Lens told Fox Sports.
“Something will have to change anything. What, we will see though. A transfer in the winter? That could happen. Once the window is open, we will see what will happen.”
Following Sunderland’s 3-1 defeat at Chelsea on Saturday, Sam Allardyce revealed Lens was omitted from the squad due to an unspecified incident after the Black Cats’ home defeat to Watford the previous week.
However, Lens added: “I know nothing. No one has spoken to me.”
