Southampton remain in the hunt for a Champions League place after a 1-1 draw at Chelsea.
Dusan Tadic equalized from the penalty spot after Diego Costa gave Chelsea the lead at Stamford Bridge.
The result has moved Southampton up to sixth position in the Premier League, three points behind fourth place Manchester United who play later against Tottenham Hotspur.
Saint's manager, Ronald Koeman, has called for his side to produce a fearless, confident performance at title-chasing Chelsea on Sunday. Despite a few bumps along the way, but Jose Mourinho's side remain on track to win the Premier League this term.
Manchester City start the weekend five points behind and with a game less than the Blues, who will can ratchet up the pressure with victory over Southampton on Sunday.
However, three points will be far from straightforward against this season's surprise package as Koeman's side look to the continue their scarcely-believable top-four tilt.
"Confidence and not afraid," the Dutchman said when asked how Saints need to approach the match.
"That's the most important when you play against big teams in an away game that you be yourself and you focus on your own game, your own way of playing, your own organisation.
"We know one of the best 45 minutes we play at home against Chelsea and that gives the team and the players confidence that we can have a good result."
While Saints have been impressive on the road, the trip to Chelsea has been made all the tougher by Wednesday's Champions League exit to Paris St Germain.
"They will do everything to win the game," Koeman said of the backlash. "That's a normal reaction because they need a win after a disappointing result.
"They have the experience to handle that, the manager has the experience to handle that, more experience than our players, and that's no question I think."
Southampton are without a win in five trips to Stamford Bridge, where last season they went down 3-1 despite taking the lead after 13 seconds.
Jay Rodriguez struck that goal but will be absent on Sunday, as he has been all season.
The England international is slowly working his way back from rupturing an anterior cruciate ligament last April and went on the recent mid-season break to Switzerland, with a return before the season is out "not unlikely".
"The reason to take Jay with the group was to give him that feeling back to be part of the group," Koeman said.
"He's doing well, he's progressing but he's still to score to be part of the squad of the team.
"He needs more time for that and he will get more time for that. Most important is the health of the player and we will see when he is back."
Philippe Coutinho's exceptional strike amid a series of controversial decisions from referee Kevin Friend helped Liverpool overcome Southampton 2-0 in what could prove a crucial result in the chase for a Champions League place.
There was no lack of vim and vigour on display in miserable conditions at St Mary's, where Brendan Rodgers' side moved within two points of the top four as the season enters the home straight.
Southampton are third in the Premier League after a late winner at Queens Park Rangers.
Sadio Mane fired a powerful shot into the top corner in the 93rd-minute in a 1-0 win at Loftus Road.
The result means Ronald Koeman's side remain in the Champions League qualifying position, despite last week's disappointing home defeat against Swansea.
Southampton held on for a 1-1 draw, at home to Chelsea. Mane scored for Saints, with Hazard equalising. Southampton's Morgan Schneiderlin was sent off near the end of the match.
Southampton have taken the lead against Premier League leaders Chelsea at St Mary's in today's early kick-off. Tadic sent Mane clear, and he lifted the ball over goalkeeper Courtois.
