Sherwood will be in charge for their Capital One Cup tie with West Ham United tonight.
“I’ve known Tim for years,” Reid told the Daily Express.
“And the thing about him you could see right from the start was that he was very self-determined and motivated. He is a winner.
“I was one of the senior players in the league when he was just starting his career, but his energy and his athleticism, coupled with his desire to get the job done meant we had some good battles over the years.
“Then, when I took over at Coventry, my task was to try to get them back into the Premier League. He was exactly the sort of leader I needed on the pitch.
“Unfortunately he arrived at us having broken his leg badly playing for Portsmouth against Spurs the season before and he never managed to get on to the pitch more than about a dozen times. But I always sensed that winning mentality was stronger when he was in the dressing room.”
