Ian Evatt believes opposite number Richie Wellens will have Doncaster Rovers well set up and pose a difficult test for his Bolton Wanderers team this evening.
Wanderers take on Donny this evening in League One as 13th take on the Yorkshire side who are currently in the relegation zone.
Wellens has had a busy past 12 months in management, moving from Swindon Town to Salford City last year before leaving the Ammies earlier this year after winning the Papa John's Trophy.

He is now at the Keepmoat Stadium, where he was a player during his playing career, with Donny currently four points from safety after 17 games so far this season.
Evatt knows Wellens well having done his coaching qualifications with the former Manchester United trainee and played up against him during his career.
Evatt admits his opposite number has had a 'topsy-turvy' year over the past 12 months, and admits Wellens is experiencing 'challenging times' at the Keepmoat Stadium at present.
And the Bolton boss is expecting a tough test against Donny as an injury-hit Wanderers take on the League One strugglers at the University of Bolton Stadium.
He said: "I know Rich well, I’ve known him a long, long time. I played against him a lot, we did our qualifications together. He’s had a topsy-turvy time but he knows the game really well.
"He’s had a good career, very experienced and tries to play a certain way. A good identity, good philosophy.
"He’s had challenging times at Doncaster – they aren’t spending the kind of money they used to and you have to find a way, and Rich is trying to do that. It will be a very difficult for us tomorrow night.
"They obviously had a good result against Lincoln on Saturday and are improving all the time. We’re depleted but as I said we have to find a way to get the right result."
