Courtois is experiencing his first festive period as Chelsea's number one goalkeeper.
They conclude their quick period of Premier League fixtures with a short trip to White Hart Lane to take on Tottenham on New Years' Day after taking four points from their games against West Ham United and Southampton.
Luckily they weren't made to pay with title rivals Manchester City letting a 2-0 lead slip at home to Burnley at the Etihad Stadium, allowing Chelsea to maintain their three point cushion at the top of the table at the halfway stage of the season.
Courtois told the club's official website that he wasn't sure there was much of a difference in the side between the games against West Ham and Southampton, saying: "I don’t know if you could see a difference because we played two days before. Maybe it’s normal if you’re a bit less strong physically so soon after playing a game but I don’t think it made any difference.
"It’s good because now we have another game coming up on Thursday against Tottenham so it doesn’t stop here."
On the Southampton game specifically, the Belgian said the team didn't start as well as they did on Boxing Day against West Ham United.
He added: "We didn’t start the match well unlike the West Ham game on Boxing Day, but after their goal we responded and equalised just before half-time. That was good because it allows you to start the second half like it is a new game."
Manager Jose Mourinho will be after a quicker start against Tottenham and hoping for a similar outcome from almost a month earlier at Stamford Bridge, where Chelsea ran out 3-0 winners.
