Chesterfield welcome Millwall to the Proact on Saturday as Danny Wilson’s men look to get back on track after the 3-1 loss to Wigan Athletic last week.
The visiting Lions sit eighth, just one point from the play-off places.
The two teams met back in August when Jay O’Shea’s double handed Chesterfield a 2-0 win at The Den. The first, a well-timed volley from outside the box gave the Spireites a half time lead before a deflected late effort confirmed the win.
The last home match saw Chesterfield smash seven against Shrewsbury Town and Millwall boss Neil Harris is expecting another tough test just like the one back in August.
Talking to Lions PlayerHD he said: “They had a great win against Shrewsbury in their last home game so we will look at their strengths. We know they have a squad with ability, just as they showed at The Den earlier in the season.
"We are coming off the back of a win in the league and we go to Chesterfield thoughtful towards the opposition, meticulous in our preparation but also focused on us and how we can create chances and score goals."
Millwall beat Port Vale 3-1 last weekend and manager Harris is hoping his side can add to that by beating Chesterfield, with a win possibly moving them into the play-off places.
He said: “We want that momentum and to build pressure on the teams above us. Our aim is to keep improving all the time and winning games gives you confidence.
Harris, a former Millwall player and now manager has been at The Den for over ten months and was quick to praise Danny Wilson for the job he has done at Chesterfield so far.
“Danny has gone in there and made a real impact, as you would expect from a senior manager. His record speaks for itself so I've got a lot of respect for him.”
