Liverpool are now closer to completing an unprecedented quadruple than any English side has ever been in terms of date.
Jurgen Klopp's side have already won the EFL Cup and remain in contention for the other three trophies available to them this season.
The Reds currently sit one point adrift of Manchester City at the top of the Premier League table, with both sides having four games left this term.
Liverpool will also face Chelsea in the FA Cup final later this month, while they boast a 2-0 advantage over Villarreal heading into the second leg of their Champions League semi-final on Tuesday night.
No English team has ever reached May 2 while still being in contention for four trophies, with Liverpool having now surpassed the previous record held by Chelsea.

The Blues made it to May 1 in the 2006-07 campaign, only to lose to Liverpool in the Champions League semi-final to end their hopes of a clean sweep.
Liverpool's charge will last until at least May 3, when they face Villarreal, and they are firm favourites to make it into a third Champions League final in five seasons.
The latest Liverpool have previously been in the hunt for a quadruple in their 24 past attempts was February 20 in 1982-83, when they ended the season with the league title and League Cup.
A quadruple has only been possible in England since the League Cup was introduced in 1960-61, with 15 different clubs having had the opportunity to achieve it during that time.
In all, there have been 120 attempts at achieving the recognised quadruple, which involves a club winning the Premier League, FA Cup, League Cup and Champions League.
As well as Liverpool this season and Chelsea in 2006-07, only three other clubs have ever made it beyond the end of March while still in contention for all four trophies.

Manchester United made it to April 19 in 2008-09, with their charge ending with defeat in the FA Cup semi-final that year.
Pep Guardiola's Manchester City side have twice seen their hopes end on April 17, meanwhile, losing in the Champions League quarter-final in 2018-19 and the FA Cup semi-final in 2020-21.
Man City's class of 2018-19 are the only one of those sides to go on to scoop three trophies from that position, winning the Premier League, FA Cup and League Cup.
The last European team to achieve a quadruple of their domestic title, two major domestic cups and the Champions League was Celtic in 1966-67, although that excludes clubs playing in a country without two domestic cups available to them.
Liverpool would need to play seven more games in order to complete the first quadruple in English football history, starting with Tuesday's Champions League showdown against Villarreal and ending with a potential final against either Manchester City or Real Madrid.
Between then, Klopp's men take on Tottenham Hotspur, Aston Villa, Southampton and Wolverhampton Wanderers in the Premier League, as well as facing Chelsea in the FA Cup final on May 14.
