The Lancashire club appointed Neil Lennon on October 12 and since then have claimed four wins and a draw from seven outings.
Such a record contrasts sharply with the one win in 14 games that preceded the Irishman’s arrival and is the reason Powell, who kick-started Town’s season following his arrival in September, is expecting a big challenge today from Wanderers.
He said: “From my own experience, I know it is normally the case that players want to impress and one or two players who may not have played before get a chance (when a new manager comes in). It has happened for Bolton.
“They drew their last game at Blackpool so you know they are in decent form, but they are below us so we have to keep it that way.
“We have to perform and we have to get results. I would like to get another result on the road.
“I think that’s important because our home form has been good – it has been strong since my very first game against Middlesbrough, as we haven’t lost at home. We just need to marry that with some points on the road, whether it’s a good away win or just a point. It’s always good to take something when you’re on your travels.”
Powell has to decide whether to restore Nahki Wells to the starting line-up after the club’s top scorer was kept on the bench for the fifth time in nine games for last weekend’s derby draw with Sheffield Wednesday.
The Bermuda international came on for the final quarter and went close to scoring a winner, to leave Powell with a decision to make.
He added: “Nahki is our top goalscorer, but, of course, sometimes I will start him and sometimes I won’t.
“Those are the decisions I have to make as a manager. But I trust Nahki because he gives his all.”
Goalkeeper Alex Smithies is back in contention after a back spasm.
