Cesc Fabregas wants Chelsea to be ruthless in tonight’s Champions League last-16 second leg with Paris St Germain.
A 1-1 draw in Paris and Branislav Ivanovic’s away goal gives the Blues a slender advantage entering the Stamford Bridge clash.
“If we can kill, we have to kill,” Fabregas said.
“When we get one goal, we have to go for the second and after the second the third. That’s the only thing we can really improve.
“Hopefully we will have that killer instinct.”
Chelsea won the Capital One Cup on March 1 and have two remaining chances for silverware this term, in the Premier League and Champions League.
Spain international Fabregas feels the League Cup win – the first trophy of Jose Mourinho’s second spell in charge of the Blues – could provide the belief for further success.
Reflecting on his experience with Spain, the World Cup and European Championship-winning playmaker said: “When we unlocked, mentally, that fear of quarter-finals or getting onto a really big stage, that’s when we felt we could become champions.
“Once we were champions we were unstoppable. That’s what we have to do. We have to believe we are the best, be mentally dominant and ready to cope with every situation.”
Fabregas is yet to win the Champions League, but hopes to do so with Chelsea following his move from Barcelona last summer.
He is looking only at the immediate task, though.
“I want to win for Chelsea, I want to give my best and hopefully we will go through into the next round,” Fabregas said.
“We’ll go game by game. Sometimes the best team doesn’t win. You have to be fortunate with the draw or your performance on the day.
“We have to take it to the next level. We want to go through. We have to make it happen.”
Mourinho accused expensively-assembled PSG of being “the most aggressive” side Chelsea have played this season, more so than League Two Shrewsbury and League One Bradford.
“With players of such quality I was expecting more football and less aggression,” he said.
“I thought an English team would never be surprised by aggression. In that game I was surprised, because a team with fantastic players was a team with the record of fouls, was the team that was making foul after foul, was the team that stopped (Eden) Hazard with fouls all the time.”
PSG, eliminated on away goals by Chelsea last term, were on top for much of the first leg at Parc des Princes.
But Mourinho bristled when asked about PSG’s dominance.
He said: “What is dominate? If dominate is the number of chances, yes, Paris had more chances than us.
“If dominate is to stop the opponent to play, making foul after foul, yes they also dominate.
“If dominate is to have the ball and to move the ball without progression, yes, they also dominate.
“I think they dominate in everything except in the result.”
The Blues boss will hope the result goes in his side’s favour again on Wednesday night and has no intention of playing conservatively.
He added: “We are going to try to win.”
