Danish defender Andreas Christensen was thrilled with his debut in Chelsea's friendly defeat to Manchester City in St Louis.
Christensen more than held his own in the 4-3 reverse.
"It was a great experience," he tells the official Chelsea website. "I was playing against top players and it was a good learning curve.
"My team-mates gave me a lot of support and helped me a lot because they have so much experience. Gary Cahill's a good player; he talked me through the game and was helping me a lot.
"The players have been great with me and made me feel part of the team, which is a big help. It was still tough, and I have a long way to go, but I felt I did okay."
