Chelsea travel to the Saint Mary's to take on Southampton as they look to maintain their top position the Premier League.
The Blues have proved that they are a force to be reckoned with, as they have been excellent this season, sitting at the top of the Premier League with 45 points from 18 games.
After a momentary setback against Newcastle United, the Blues seem to have returned to their winning ways with three back-to-back victories against Hull City, Stoke City and West Ham United.
Their statistics in the Premier League have been excellent this season as they have scored the most number of goals (40) and conceded the fewest (13).
However, the Blues will still be a little wary ahead of their trip to the Saint Mary's as Southampton have been playing well in the Premier League this season, where they are currently in fourth place.
And Chelsea boss Jose Mourinho feels that the Saints are doing well this season due to them having landed the right replacements for the players they lost in the summer transfer window.
"Southampton lost some good players but they were very clinical in their choices [for replacements], so they have a good squad, a very good coach and they are playing well."
The Portuguese also feels that the Saints have the liberty to play some attractive football against Chelsea due to them being far away from the threat of relegation.
"They are getting results and they are the kind of team that in this moment has no pressure as relegation is very far away and the title is not for them," added Mourinho. "So they are in a fantastic situation to play beautiful football like they are doing."
Meanwhile, Southampton will also be looking to get a positive result on Sunday though they have failed to beat any of the top teams in the Premier League this season.
Despite doing brilliantly against the likes of Newcastle united (4-0), West Ham United (3-1) and Sunderland (8-0), the Saints failed to muster up the same enthusiasm against the big teams and this resulted in them recording three back-to-back defeats against Manchester City (0-3), Arsenal (0-1) and Manchester United (1-2).
Although Ronald Koeman Chelsea will certainly prove to be very tough opponents for the Saints, manager Ronald Koeman is confident that they will do well if they play with confidence and belief.
"I think the team is looking forward again with a lot of belief in how we play in a different system. They show they are very comfortable and that's important. That makes winning easy if you play with that confidence," the Dutch boss told the Saints official website.
The former Feyenoord boss feels that Sunday's game is a challenge for his side following their consecutive wins over Everton and Crystal Palace in the Premier League.
"It's a challenge and we will take that after a comfortable win against Crystal Palace. We know we have to be very good for a result but the two wins bring the team a lot of belief and we need that for Chelsea."
