Scott Sinclair was used only from the bench as Celtic beat Rangers on Sunday.
Former Rangers striker Steven Thompson has claimed on BBC Sportscene Extra's Facebook Live channel that Scott Sinclair could leave Celtic at the end of the season, after Brendan Rodgers used him as a sub against Rangers.
The 29-year-old was left on the bench by Rodgers during Celtic's 4-0 win over Rangers on Sunday in the Scottish Cup, only coming on in the 61st minute to replace Tom Rogic.
The former Manchester City star has still impressed despite no longer being one of the first names on the team sheet this season, scoring 17 goals and supplying 17 assists in 49 league and cup outings.
Thompson said he would not be surprised if Sinclair left Celtic Park at the end of the season, stating that the Hoops have plenty of options out wide in the likes of Charly Musonda, James Forrest and Jonny Hayes.
"It wouldn't surprise me," Thompson said, when asked if Sinclair will leave. "I don't think he has had the season he would have been hoping for given last season just how good he was. He's definitely played below the level he set last season.
"It seems to me Celtic have an awful lot of players in wide areas. Jonny Hayes will be back fit, Lewis Morgan of St. Mirren, Ryan Christie will be back from his loan spell. Musonda is there for another year, they have a plethora of options."
Sinclair, who has also played for Swansea City, Aston Villa and West Bromwich Albion, has two years remaining on the four-year deal he signed in the summer of 2016 - which the Daily Star claim is worth £25,000 a week.
It remains to be seen whether Rodgers will look to keep Sinclair, as Patrick Roberts is expected to rejoin Manchester City in the summer at the end of his loan at Celtic.
