The goalkeeper joined Chelsea from New England Revolution in the summer and has started our previous five matches in all competitions following an injury Robert Sanchez sustained against Everton.

Petrovic impressed with his first clean sheet in the win over Sheffield United and emerged as the hero from our penalty shoot-out victory over Newcastle United in the Carabao Cup quarter-finals, saving the decisive spot-kick from Matt Ritchie.

While the 24-year-old may be relatively experienced for a goalkeeper of his age, with 134 top-flight appearances under his belt in the USA and his native Serbia, Petrovic admits the challenge of the Premier League has been a big step up.

‘It's like a completely different sport,’ he explains. ‘It is a lot faster and you don't have time to think when you have the ball at your feet.

‘It is different, but I enjoy it here because it is a dream. Everyone wants to play here and you can improve quickly.’

The pressure that comes with being a Premier League goalkeeper is unique. Every save is scrutinised; every incident is highlighted and replayed. Petrovic has handled that spotlight – and the expectations placed upon a Chelsea goalkeeper – well thus far.

‘It is not easy because we play for a big club, one of the biggest clubs in the world,' he says. 'Every game we want to win and we want to take trophies and titles.

‘We have pressure, but my team-mates help me a lot every time, and I try to help them. The coaching staff at training and in the games are also helping me and everyone.’

Being part of a tight-knit group of goalkeepers helps, and Petrovic is quick to highlight the importance of the advice his fellow stoppers gave him ahead of his full debut against Sheffield United, which ended with his first clean sheet in English football and a 2-0 win.

‘Everyone is helping,’ continued Djordje. ‘The goalkeepers and goalkeeping coaches support each other and there is a good chemistry between us. Everyone speaks before and after training.

‘If I have something to ask Betts [Marcus Bettinelli], Robert [Sanchez] or Lucas [Bergstrom], we all help each other, and I am also helping them.

‘Before my first start I felt the pressure to be honest, but they came and said to me: “no pressure, just play your game”. So that’s what I did.’

He certainly seems to have overcome the pressure quickly in his early appearances for Chelsea, which will no doubt hold him in good stead as the games continued to come thick and fast, starting with cup ties against Preston and Middlesbrough before we return to Premier League action in a west London derby with Fulham.
