Sinclair faced Carson during the Scottish Premiership game against Motherwell away from home at Fir Park on Wednesday evening.
Former Aston Villa winger Sinclair was impressed with the performance of the former Sunderland prospect in the 1-1 draw.
“The Motherwell keeper was great,” Sinclair told The Scottish Sun about Carson. “He made some great saves.”
Celtic manager Brendan Rodgers was also impressed with Carson and also spoke highly of him to Herald Scotland.
Carson joined Motherwell only in the summer transfer window, and his performances in the Scottish Premiership so far this season have been very encouraging.
Perhaps Celtic should keep an eye on the former Bury star and monitor him as the season progresses.
The Bhoys could do with a new goalkeeper in their squad to compete with Craig Gordon, who is prone to making mistakes and is the clear first choice at Celtic Park.
