"He's someone you would rather have in your team than against you. "He's a big man in the dressing room and gets the guys playing like Vaughany (captain Michael Vaughan) does. To have him on our side has been incredible."
At 27, Flintoff is three years younger than Vaughan but has had limited experience of captaincy at county level with Lancashire.
Bell added that he was surprised to have played all of England's summer Tests. The 23-year-old had the lowest average of all the specialist batsmen, managing only 17.10, but said that he was not fazed by statistics.
"I never expected to play all seven Tests for England at the start of the summer," said the Warwickshire star.
"The memory of winning the Ashes at The Oval is something I'll never forget. I'll also always remember winning at my home ground, Edgbaston, and the noise. "It's a team game at the end of the day. I'm happy the way I contributed all the way throughout the series.
"I never got the feeling from management, players or selectors, that I would be dropped. " Having been selected for England's winter tour, Bell said he was looking forward to another new challenge.
"It'll be a tricky winter. To play Pakistan and India in their own backyard will be tough cricket," he added.
"I'd love to go out and score runs. But as long as I can keep learning and become a better player, I'll be happy."
