Tony Pulis has come under pressure at West Bromwich Albion this season.
Evans moved to the Baggies from Manchester United last summer, and he has been handed a key role at the Hawthorns.
The centre-back has already made 21 appearances for the Baggies this term, and become their most integral defender.
And the Northern Ireland international has been impressed by Pulis’ managerial style so far.
“Winning games in the Premier League is such a big thing, especially for a club like West Brom, and the feeling when you achieve that is fantastic," the centre back said. "And one thing I would say about Tony Pulis is that I have been very impressed by how he gets his team working really hard. He is a great motivator.”
Pulis has come under pressure at West Brom this season, due to his preferred style of play.
The former Stoke City and Crystal Palace boss is renowned for his defensive approach, and sections of Baggies fans have grown frustrated with the lack of entertainment on display.
West Brom have not shown as much attacking ambition as some of their supporters would have liked, but their season still has to be considered a success.
The Baggies are currently in 13th place in the Premier League table, and they have built up a 12 point cushion on the bottom three.
The Baggies have also taken seven points out of the last nine available, and their next fixture comes against Manchester United at the weekend, where they will be looking to extend their good run of form.
