Colchester United head to Meadow Lane in a battle of two of League Two's form sides.
Only Luton have matched the points collected by John McGreal's men in the last ten matches, as the U's have thrust themselves into the thick of the promotion race in the last few weeks.
They also top the recent away form table but come up against a Notts County team who top the home form table over the same period.
An intriguing match therefore lies ahead for John McGreal's men, who have kept six clean sheets in their last nine league matches.
Speaking at Thursday's press conference, John said: “It’s going to be our biggest test of the season by far.
“It’s going to be a huge task for us but we’re in a great run of form ourselves and it’s great to try and pit your wits against a top team.
"We found it tough when we went there last season but now it’s a little bit different and we’re in a little bit of form.
“But they’re in great form as well and sitting joint top. It should be a good game and one we’re really looking forward to.”
The U's are set to be without Doug Loft after he came off with a shoulder injury in the 1-0 win over Lincoln City, but otherwise the team are in good shape prior to the trip to Nottingham.
