The former Napoli captain joined the Blues in the summer and was billed as the ideal replacement for the outgoing Antonio Rudiger.
Thomas Tuchel was delighted to have recruited a player of Koulibaly’s experience but the 31-year-old has found adjusting to the Premier League far from straightforward.
The German’s demise and recent sacking has thrown another spanner in the works for Koulibaly who was dropped for Potter’s first game in charge against RB Salzburg earlier this month.
Potter opted to select club captain Cesar Azpilicueta in an unfamiliar central defensive role and Marc Cucurella, who he coached at Brighton, at left-back.
Koulibaly insists he understands Potter’s decision and has been impressed with the early impact Tuchel’s successor has made.
He told Le Quotidien : ‘The new coach came with some good ideas. He’s a real coach. He did some good things with Brighton. Now he is a Chelsea manager.
‘He has guidelines, expectations. It’s up to me to be patient, it’s up to me to show that I deserve to play, to show in training that the coach can trust me.
‘Compared to this, there will be no problem. We are also in the first weeks, it is normal for the coach to rely on players who are used to the emblem of Chelsea and who have been there for a very long time.
‘When I will be at 100%, there will be no problem, I will play again.’
Despite the less than auspicious start to his career in England, Koulibaly has no regrets about signing for Chelsea and insists the decision to sign was a straightforward one once he learned of their interest.
He added: ‘You know, it’s a life choice. I wanted to change clubs. I felt like I’d given everything to Napoli. There came a point where I wanted to change life, challenge myself and throw myself into a new challenge.
‘Chelsea arrived and it didn’t take long for me to choose. They’re one of the five best clubs in the world, with a great history; a team that’s used to winning.
‘When they called me, I immediately gave a positive answer because it was also admirable to play in the Premier League. I’d played in France, Belgium before arriving in Italy, where I grew, matured and where my children were born.
‘Therefore, I’ll never stop thanking them for what they gave me. Now, I felt it was time to discover something else.
‘Signing with Chelsea was a very good thing for me. I’m very happy to be there. It was a bit tough at first, because I had to move eight years of my life to London. It’s something that’s quite hard.
‘The need to find a school, get used to the London life. I arrived in London, where I found my house, the school for my kids. I’ve found my bearings, so I’m very happy.’
