When Port Vale hosted Walsall in early December, their 1-0 home defeat that day cost Darren Moore's men the leadership of League Two to the Saddlers.
Vale now have the chance to return the favour when they head to Bescot for this Saturday's return fixture.
After taking over on top that day, Mat Sadler's Saddlers have been there for four months since, at one point building up a 12-point lead. But that has slowly been whittled away - and, if Vale win, Walsall will be knocked off the top.
What is more, if Vale's local rivals, eighth-placed Crewe Alexandra, can avoid defeat by second-placed Bradford City, then Moore's Valiants could be back on top.
The one key element different to the game in December is that this time Vale will have the services of their skipper, midfielder Ben Garrity, who was out injured when the first meeting of the two sides took place.
The effect his presence has on Vale is stark. This season, in 26 League One games with him in the side, they have lost just three. In the 14 games without him, they won just twice and slumped from top spot to outside the top six.
'We want to hear cheers, not groans'
The message from both camps ahead of the return is one of solidarity and team spirit.
Sadler said that his squad are solely focused on maintaining the quality of their performances, and that the rest will take care of itself - but he added that his team now need the home fans more than ever, and that he also needs that same togetherness in his players.
Garrity is even clearer in his plea to the Vale fans - at home games, rather than on the road - to try and cut out the groans.
When Vale scored their opening goal in Tuesday night's 2-0 home win over Bradford City, it came straight on the back of Garrity playing a reverse pass backwards, for which he got some groans from the crowd - and to which he reacted.
"I've gone a bit mad there because I'm sick of hearing groans," he told BBC Radio Stoke.
"It happens a lot at home when players make a decision not to play the ball forward and keep it instead, but sometimes you need to slow it down and keep hold of the ball when we're under the cosh.
"I played it back, it then went forward and then we scored. I lost it and I'll lose it again if it happens. I thought it was only right for me to react the way I did."
Garrity added: "We want to go forward and score goals. And, when the fans are right behind us, it's brilliant. But what are the groans for?
"We want to keep the ball. We don't want to chase it for 90 minutes. And, if you're ...
