NORTHAMPTON boss Rob Page has warned that Millwall's form "can turn at any time" ahead of the meeting between the sides on Saturday.
Page, who took over Northampton in the summer, said Millwall were "outstanding" as they finished fourth in League Two in Neil Harris' first season in charge.
Northampton have exceeded expectations so far under Page, who was in charge of Port Vale last season when they lost 2-0 to Millwall at home (above) and 3-1 at The Den. The Cobblers sit in sixth place in the table, six points ahead of Millwall in 19th.
Millwall haven't won in the league since the 3-1 victory at Chesterfield on August 27, but Page urged his players to be on "guard" this weekend.
"Everybody has a bad spell in this division, everybody does," Page told Northampton Chronicle and Echo. "Millwall's record isn't great at this present time, but that can turn at any time and we have to make sure that it's not on Saturday.
"I know the manager, I know how he goes about his work, and their form will be hurting him. He will be working ever so hard to put it right, and so will the players that he has got.
"They were outstanding in the division last season, and they will get there again, so we have to be on our guard and make sure we go and impose ourselves on them on Saturday, and focus on what we can do."
"Millwall are a big club in this division who did well last season, so it will be a great guage for us.
"But, as always, we know that, irrespective of who we play against, if we perform to our level consistently we are a match for anybody."
