Cesc Fabregas has much to be happy about Chelsea's season so far but he called on his side to be more ruthless when they have opponents by the jugular.
The Blues have been dominant in the Premier League by and large but have let leads slip and, infamously, let a 2-0 lead at home to League One Bradford slip in the FA Cup fourth round.
Chelsea have the advantage of an away goal over Paris St Germain going into the second leg of their Champions League last 16 meeting and the Spaniard does not want to let that fade and send the Blues crashing out of the competition .
He said: “This is the thing: if I have to say what we're missing a bit this season it's that moment when, if we can kill, we have to kill.
“There have been moments where we've not done that and allowed other players to push and be dangerous.
“We have to be more determined, especially when we go forward. When we get one goal, we have to go for the second and third.
“That's the only thing we can really improve. Hopefully we will have that killer instinct tomorrow and go for the game from the first second.”
