As reported by Standard Sport on Tuesday, the Chelsea boss was undecided whether Gary Cahill would return to the starting line-up having been left on the bench for the weekend win at Stoke.
With Andreas Christensen impressing alongside Antonio Rudiger, and with David Luiz available having missed the Premier League clash through suspension, Conte had plenty of options available.
But it appears Conte has opted for the tried and tested, with Luiz and Cahill expected to start.
Elsewhere, Eden Hazard is also expected to get his second start of the season, having played from the offset in the League Cup tie with Nottingham Forrest.
Here is how Standard Sport’s Simon Johnson, who is out with the team in Madrid, expects Chelsea to line up…
How Chelsea could line up against Atletico
Chelsea (3-4-2-1): Courtois; Azpilicueta, Luiz, Cahill; Moses, Kante, Bakayoko, Alonso; Willian, Hazard; Morata.
Cahill believes that an opponent such as Atletico offers Chelsea a great chance to show their credentials.

Speaking to Simon before the match, he said: “This is going to be one of our hardest games in the Champions League. It doesn’t get much tougher, so if we can get a result there it will say a lot.
“This is a proper tie. We are not just coming up against technicians and people who are really good on the ball, but they are real men, physical.
“They have the attributes you are looking for in a team. They tick most of the boxes.
“We know a lot about Atletico. We have seen them in European competitions in recent years. They have done very, very well and there is a reason for that.
“It’s going to be a real challenge but we got a draw over there in the first leg of the semi-final in 2014, which we thought had set us up great for the second leg, only to lose. It is important we come back with something.”
