Gary Cahill is putting his trust in security experts to decide whether Chelsea's Champions League trip to Maccabi Tel-Aviv will go ahead on Tuesday.
The latest information from the British government advises tourists to "take extra care and be vigilant when using public transport in Tel Aviv," saying that there is a "high threat from terrorism" in Israel.
The Premier League champions are playing 60 miles north of Maccabi's home ground due to the club playing European games at the Sammy Ofer Stadium in Haifa due to a higher capacity, and Chelsea can qualify for the knockout stages if they win and Dynamo Kiev fail to beat Porto.
Cahill represented England in Tuesday's friendly against France just four days after the Paris terror attacks, and the defender is confident of the safest decision being made by officials ahead of Chelsea's game.
"You just rely on people who know a hell of a lot more than me about the whole situation to make sensible decisions," The Sun reports Cahill as saying.
"We have played in the right manner against France on the international stage and the security was fantastic from what we saw, so the decision was right.
"For our trip to Israel you rely on people who know more than us and they ultimately make the decisions."
A Chelsea spokesman is quoted by The Sun as saying: "We keep our security measures under constant review."
Cahill won the Champions League in 2012 having joined Chelsea that January, and is eager to follow up the success of his debut campaign with the Blues this term despite their poor domestic form.
"If we win there we have Porto at home to see who could end up top," Cahill added. "It's important that we do as well as we possibly can in that competition given our slow start in the league.
"Of course we're looking for things to pick up. When I came in it was a difficult season because they were underachieving at that time and were way down the league.
"We managed to go on and do an incredible thing, which was to win the Champions League. But you see from the history of the club that it's very difficult to do that.
"Since that we got into the semi[final] against Atletico Madrid and we're looking to push hard in that competition now. We're respectful of how hard it is to win the competition with what you have to go through. First and foremost we have to get out of the group."
