Notts County v Sheffield United, Wednesday 19:45, Sky Sports 1, Match Odds: Notts County [2.5], Sheffield United [2.9], The Draw [3.4]
This all-League One tie brings together two of the division's top five teams and two of the Football League's most famous names to boot.
It's also a repeat of the league meeting from just over two weeks - a 1-1 draw at Bramall Lane - so the evidence points to a fairly tight affair.
Sheffield United are now unbeaten in their opening 12 league matches and currently occupy third spot, although seven of those have ended in draws for the Blades.
If Danny Wilson's men had converted four of those draws into victories then they would be shoulder to shoulder with surprise early leaders Tranmere.
A particular source of frustration to United fans will be the last four home league games which have ended in parity, so the fact this tie is away - where the Blades have
won their last three - will likely come as some relief.
After a blip against Walsall, the home side were enjoying their own extensive unbeaten run of seven games before succumbing to the top two sides in the division at home in recent weeks.
A 4-0 stuffing of Carlisle on Saturday was the perfect remedy for Keith Curle's County to get back on track and it's really difficult to pick a winner here, with the draw after 90 minutes a real tempter at [3.4].
This fixture finished 1-1 just a few weeks ago and it's difficult to predict a goal glut here either between these two evenly matched promotion seekers.
Astonishingly, just one of Sheffield United's last eight games has made it over the 2.5 goals mark since their 5-3 thriller against Bournemouth on September 1.
If Sheffield United had a prolific striker then perhaps they would be in the position that Tranmere are right now.
However, in Nick Blackman they have a man in form - with two from his last two - and as the nominated penalty taker he is always going to be in the reckoning for a goal.
