Stuart Gray says his Northampton Town players must 'stand up and be counted' if they are to make the most of their game in hand at Stockport County.
Town head to Edgeley Park on the back of two straight away defeats in the league and in the bottom four of the Coca-Cola League One table.
They also face a fired-up Hatters side bristling from a fine 3-0 win at Leyton Orient at the weekend.
Stockport came up through the league two play-offs last season and have built a reputation for being a tall, strong side.
Gray is hoping to have two powerful players of his own back for the game in Chris Doig and Adebayo Akinfenwa, and says it is important his men match the home side's physicality.
"We need to go to Stockport and stand up and be counted," he said.
"I don't think it's going to be a physical game as such, but they've got some big players and they will play to that strength.
"They scored a couple of their goals at Leyton Orient from set-pieces so they will be a big threat from them.
"We need to cut it out at source and compete with them for the ball.
"I'll stand by my principles of how I want to play, but you do have to defend set plays.
"We're not the tallest team at the moment, so we might have to have a bit of a look at that, and we'll have to keep an eye on Liam Davis with that in mind as well."
