"It's been a year I've really enjoyed, so to have that role again for another year is great for me," said 34-year-old Tindall, who has racked up 61 European appearances overall.
"We had to make certain recruitments in certain areas, so we had to make sure we strengthened the squad in the right way, but then after that it was only about dotting those I's and crossing those T's on the deal.
"Definitely it's been my best season in the last few years. I've embraced the way that Nigel has been a breath of fresh air, letting the players go out and play, and making it very simple.
"He's made it a very positive atmosphere where people can just go out and enjoy themselves. I think that's probably why you've seen us make the progress we have this year.
"Consistency is the big challenge next year, of course. To lose to the two teams at the bottom but then beat all the top four at home, and most of them away, that tells its own story.
"But if we can make the same progression as we have this year next term, then I think we'll be in a really strong place.
"It was certainly a bit of a sticky patch last year, the club was a bit up in the air itself, so it was hard for me to get any real straight answers at that point.
"But luckily enough I held on and held on, Nigel came in, was very supportive and we managed to get something sorted.
"And now we're looking more long-term again, and that's great for me and hopefully great for the club."
