Leeds United only require a point to seal automatic promotion to the Premier League after beating Barnsley 1-0 at Elland Road.
Barnsley defender Michael Sollbauer's own goal in the first half was enough for all three points in what was a cagey affair between the two sides.
Whites boss Marcelo Bielsa will be delighted, however, with a victory which means his side are now on the brink of sealing a first return to the top flight since 2003/04.
Leeds are now on 87 points, five clear of second placed West Brom and six ahead of third-placed Brentford.
If West Brom fail to beat Huddersfield on Friday evening, Leeds will be promoted before they face Derby County on Sunday.
In the aftermath of the Barnsley win, Arsenal striker Eddie Nketiah took to social media to congratulate his old side.
The young forward spent the first half of the season on loan at Elland Road, but struggled for regular starts with Bielsa preferring to select Patrick Bamford.
But Nketiah has clearly taken away good memories of his experience at Leeds, as he replied to the official club account with a heart emoji.
Speaking after the game, Bielsa reflected on his side's performance against Barnsley.
"Even if in the first half we didn’t have a big impact we could control the match to create some chances," he said in his post-match press conference.
"In the second half we couldn’t control the match. It was difficult for us to defend. Team in attack had a lot of players that can unbalance the match.
"In the match progressed tghey added more offensive players and removed defensive players. We organised ourselves to resolve the adaptation we had to resolve.
"Difficult for us to defend well and we didn’t attack well in particular."
