Will Leeds cling on in League One?
The battle for the second automatic promotion spot in the third tier of English football is not normally much of a headline grabber, but this year is very different.
On Saturday, Leeds, Millwall, Swindon, Charlton and Huddersfield will all fight for the right to join Norwich in the Championship next season.
And the equation is simple: five into one doesn't go.
Leeds have done their best over recent months to mess up what looked like an assured march towards promotion. They led the table by eight points at the turn of the year and had just beaten Manchester United in an FA Cup third-round tie. But then it all turned sour. Having been beaten only once in the league prior to the game at Old Trafford, they suffered an alarming slump in form, including a four-game losing streak that saw them drop to fourth in the table.
Leeds recovered and will probably scrape over the line after winning four of their last six games, but nothing is guaranteed, even when faced with what looks like a very winnable match at home to Bristol Rovers.
Any sort of slip-up by Grayson's team could be punished severely, with Millwall and Swindon in prime position to capitalise. Both teams lie just a point off second and face each other at the New Den on Saturday.
Only champions Norwich have a stronger home record than the Lions, who are unbeaten at the New Den since late November. As for the Robins, strike duo Billy Paynter and Charlie Austin have helped Danny Wilson's team threaten, although three draws in four games have damaged their chances.
Charlton kept alive their hopes of automatic promotion by defeating Leeds at The Valley on Saturday. Phil Parkinson's team need to win at Oldham and hope that Leeds lose while Millwall and Swindon draw. I don't think it will happen, but League One has rarely followed the script this season.
Huddersfield, three points behind Leeds, are the real outsiders. They need all the results involving their promotion rivals to go their way while dishing out a thrashing at Exeter to address their inferior goal difference.
While most of the focus is likely to be on the battle for promotion from League One, there is plenty at stake at the other end of the table.
It looked as though Gillingham, Exeter and Tranmere would scrap it out to avoid the fourth and final relegation place. But then Hartlepool joined them in the mire on Thursday when they were deducted three points by a Football Disciplinary Commission for fielding an ineligible player in their 2-0 win over Brighton in April, although on Friday the north-east club said they intended to appeal against the decision.
Tranmere are currently in the drop zone, trailing Exeter on goal difference. Hartlepool are a point better off while the Gills have a two-point advantage.
Rovers, who defeated Millwall last weekend, travel to rock-bottom Stockport, Exeter, who have not won in six, host Huddersfield, while Hartlepool visit Brentford. As for Gillingham, the only Football League team without an away win all season, they end their campaign with a trip to relegated Wycombe.
The three automatic spots in League Two are all sown up, but two play-off places are still up for grabs, with six teams in the frame.
Morecambe (70) and Dagenham & Redbridge (69) are the current incumbents, while Bury (68), Port Vale (67), Chesterfield (66) and Northampton (66) are hot on their heels.
At the bottom, Grimsby and Barnet are desperate to avoid the drop to the Blue Square Premier. But, barring a remarkable set of results that could see Cheltenham relegated, either the Mariners or the Bees will join Darlington in dropping out of the Football League.
It seems remarkable that a team that went on a 25-game winless streak between September and February could still avoid the drop, but that is the very real possibility that confronts Grimsby. They defeated Barnet at Blundell Park last Saturday and have won four of their last six games as they prepare to travel to Burton for their final fixture.
Barnet opened a top-class training facility earlier in the season, but their ambitious plans could lie in tatters if they do not defeat promoted Rochdale on Saturday. "It would rip the heart out of us," admitted Barnet chairman Tony Kleanthous.
The Bees were relegated from the Football League on the final day of the 2000/2001 season and will be keen to avoid an unwelcome repeat. In an effort to beat the drop, manager Ian Hendon was dismissed and Paul Fairclough handed the reigns. It was the first time in 16 years that Kleanthous had sacked a manager, but he felt he had no other option.
Fairclough's reign began with defeat to Grimsby, but he has promised fans that his team will win this weekend. I wonder whether Barnet supporters feel quite so confident.
In fact, whether you support Leeds, Millwall, Chesterfield or Gillingham, I want to know what your thoughts are ahead of what is a crucial weekend.
