Chelsea will fight until the last minute of every match to secure a top four place in the Premier League, manager Maurizio Sarri has said.
Chelsea are sixth on 56 points, two behind fourth-placed Manchester United and one behind Arsenal, who play each other on Sunday. Sarri's side have played a game less than their top-four rivals.
"We will be fighting for the top four until the last minute of the last match. Every match will be important in our future," Sarri told reporters ahead of Sunday's league match against Wolverhampton Wanderers.
"We have two big opportunities, this match [against Wolves], and when we play the match [in hand] against Brighton."
Chelsea have beaten Tottenham Hotspur and Fulham in the league, as well as Dynamo Kiev in the Europa League, since their shoot-out defeat to Manchester City in the League Cup final.
"In five matches we conceded only one goal. Now we are improving in consistency, we are improving in defensive solidity, but we have to be careful," Sarri added.
"In the past we had a long period of results, and then suddenly two weeks of disaster."
Sunday's match is Chelsea's ninth in 28 days and Sarri said their participation in the Europa League had forced him to rotate his squad to avoid any potential burnout.
"In this moment it's very difficult to arrive to every match with the same level of determination, mentally and physically at 100 per cent. But for the next match we can change six or seven players," Sarri said.
Also in action Sunday are second-placed Liverpool, who travel to Turf Moor to play Burnley.
Defender Dejan Lovren could return to Liverpool's squad after a two-month absence with a hamstring injury.
The Croatia international was back in full training on Thursday but manager Jurgen Klopp has yet to decide whether he can be thrown back into the action.
"He was out for a while, so we have to see how his fitness is exactly," Klopp said.
