Chelsea defender Gary Cahill has warned his teammates to focus on their remaining games instead of thinking about their own futures.
The reigning Premier League champions had a horrendous start to this campaign, resulting in Jose Mourinho leaving the club and the team some 14 points behind leaders Leicester City, despite an emphatic 5-1 win over Newcastle United on Saturday.
The only chance for Chelsea to qualify for next season's Champions League will be to win the competition this year, but a stern test awaits them when they travel to France on Tuesday to take on Paris Saint-Germain in the first leg of the round of 16.
With such a massive game ahead, Cahill who recently signed a four-year extension with the club, reiterated his commitment and has urged his teammates to follow his example.
"This club doesn't need to sell itself to anybody. Everyone knows this club is very successful," he told The Express.
"You'd like to think this year is a slip-up in the league if we do not finish in the top four.
"Everyone is under contract and has competitions to fight in as hard as they possibly can if they have any ambition to win. What happens in the summer, happens in the summer.
"Everyone should be ambitious. Nobody should be looking anywhere else but focusing on winning something this season."
Cahill, who was part of Roberto Di Matteo's side that won the Champions League and FA Cup in 2012 -- Chelsea finished sixth in the league that year -- is confident the club can repeat those heroics to finish the season strong.
"I remember thinking at the time that we're going to have to win this to get back into the Champions League. It was all about the next game and the next game. We can't look too far beyond that.
"I had the experience of going all the way and it lives with you forever. We have to prove that we're a good team and good players on the biggest stage. This game is massive."
Chelsea will be mindful of last year's painful exit, when Laurent Blanc's team sent them out of the Champions League at the same stage.
Hiddink will be banking on Diego Costa's resurgence, having scored eight goals in his last 10 matches. Captain John Terry is in doubt with a hamstring injury.
