Leeds come to Griffin Park facing three very different fixtures to end their season. United have to host high-flying Aston Villa next weekend, just before they face already-relegated Ipswich Town. Brentford are the team in the middle of that, not going up or down but boasting an impressive home record.
At Elland Road in October, Pontus Jansson was the hero after a Neal Maupay penalty had put The Bees in front. Luke Ayling was also sent off that day in the final minutes of the tie.
Leeds lost their last match to Wigan Athletic, putting them third in the table on goal difference, made worse by the fact that the Latics were reduced to 10 men in the first quarter of an hour.
United have won three of their last four on the road, losing that fourth to Birmingham City at St Andrews. The side have guaranteed themselves a play-off place but automatic promotion is still a large possibility. Fans will certainly feel like this is the best chance they've had to get back to the top flight for the first time since 2004.
Goalkeeper Daniel Bentley is out for the rest of the season, as is Said Benrahma following the game against Reading last week. Henrik Dalsgaard is suspended after he was shown red in our 1-1 draw with Millwall on Good Friday.
Yoann Barbet and Lewis Macleod are both doubtful. Julian Jeanvier missed our match with Millwall due to illness and, along with Rico Henry, could return to the side for our penultimate home match.
For Leeds, captain Liam Cooper was injured during the warm-up against Sheffield Wednesday and missed the defeat to Wigan. He will likely miss this one as well with a muscle problem. Barry Douglas will definitely miss out, while Gaetano Berardi could return.
Marcelo Bielsa, 63, is an Argentinian manager who played the game as a defender for the likes of Newell's Old Boys and Instituto in the late 1970s. Retiring early at the age of 25, he decided to dedicate his career to coaching. In 1990 he was given his first role as manager at his old club for two years.
In 1998, he had a brief spell as Espanyol manager before leaving to take on the job of Argentina's national coach. He had a six-year tenure of his native side, qualifying for the 2002 FIFA World Cup and also won the country a gold medal in the 2004 Olympic Games - their first in 52 years.
From there he went on to manage Chile in 2004, taking them to the 2010 FIFA World Cup and acheiving a Last-16 finish. They lost 3-0 to Brazil in front of 54,000 fans at Ellis Park Stadium. Spells at Athletic Bilbao, Marseille and Lazio and LOSC Lille followed before he was appointed Leeds boss in June this year.
