Barcelona and Real Madrid both won on Saturday, meaning the title could be decided next weekend.
Cesc Fabregas' 84th-minute strike earned a below-par Barcelona a narrow victory over Levante at the Camp Nou as they remained 13-points clear at the summit.
David Villa had seen a 16th-minute penalty saved by Keylor Navas, and that looked like it would prove a costly miss as Barca - perhaps with one eye on Tuesday's Champions League semi-final first leg against Bayern Munich - struggled to break down a spirited Levante defence, before Fabregas' late breakthrough.
The win means Tito Vilanova's side, 13 points clear of second-placed Madrid, could win the title next weekend, despite Real's 3-1 win over Real Betis earlier in the evening.
Mesut Ozil scored twice to ensure Real Madrid will go into their Champions League semi-final clash with Borussia Dortmund on the back of a Primera Division win.
Germany international Ozil broke the deadlock against Real Betis on the stroke of half-time and then wrapped up the scoring with his second right at the end.
In between those two strikes, Karim Benzema had put Madrid 2-0 up before Betis pulled a goal back through Jorge Molina's 73rd-minute penalty.
Granada are a point clear of the relegation zone after coming from behind to draw at home with Real Valladolid.
Patrick Ebert gave the visitors a surprise lead in the second half with a gloriously struck free-kick but Youssef El-Arabi levelled with 18 minutes remaining.
The hosts were the better side throughout the 90 minutes and pushed for a late winner but were unable to beat the outstanding Valladolid goalkeeper Jaime Jimenez.
The third-placed Bees will meet second-placed Rovers at Griffin Park to decide the final promotion spot in League One, with Rosler's side two points adrift after their 1-1 draw at already-relegated Hartlepool.
Victory is a must in the game, and Rosler admitted: "We have worked so hard in the last few months to be in the position where we have it in our own hands and now it all leads to the final day.
"It's a home game and we have enjoyed a great achievement in getting there - Doncaster have everything to lose and we have everything to gain."
He continued: "This wasn't the greatest game by any means, in the 25 minutes until they scored we were not at the races, then we lose our nerves.
"When we started to attack we scored and then in the second half we were the better team and had some very good chances.
"Tom Adeyemi had two chances to win the game, we know we can all play better, no question about it.
"Credit to Hartlepool, they showed character and didn't drop their heads after relegation.
"But we are where we want to be and are full of optimism - now we look forward to a full house at Griffin Park."
Pools started well and were good value for their lead, which came after 25 minutes when teenage prospect Luke James fired in after Jack Baldwin's shot had been cleared.
The promotion chasers levelled after 39 minutes when goalkeeper Scott Flinders, the club's player of the year, made a diving save to keep out Jonathan Douglas' header and Marcello Trotta turned to fire home a low shot.
The Bees did not create much in a flat second period, with their best chance coming in the 87th minute when substitute Tom Adeyemi broke into the area but Peter Hartley blocked his shot.
Hughes said: "In the last 15 minutes of the first half it was Brentford who got a hold in the game and in the second half it was backs to the wall.
"We had three young kids out there playing against a team who are going for automatic promotion, which will do them the world of good.
"In terms of effort it was different class, it's a real tricky playing surface, conditions weren't great for everyone and I wish Brentford all the best in their pursuit of promotion.
"We kept our focus on the game and we need to sit down and won't make any knee-jerk reactions after relegation."
