Andreas Christensen says he's returned to Chelsea a much better player for two seasons away with Borussia Monchengladbach.
The Danish defender is back after an extended loan spell in Germany.
The told the London Evening Standard: “I have come back to Chelsea a better player than the one that left two years ago. I played about 80 games in two seasons and I have a lot more experience. I have a bit more toughness, more mental than physical.
“The physical side of things is something I still have to build on, but mentally it has given me a lot. I'm more confident, I feel ready for bigger things. I was up against a lot of top strikers, big teams. I remember when I played against Bayern for the first time, I was nervous beforehand because it is easy to look like a clown playing against these guys.
“Borussia played one against one at the back and I was directly up against (Robert) Lewandowski first and then (Thomas) Muller later on, but we won the game 3-1. Everything went well and this is the kind of thing that gives me more self-belief at the top level."
Christensen added: “I haven't spoken too much (with Antonio Conte) about it (his role), it's just about getting all the tactical work in.
“Right now I'm concentrating on just trying to learn what he wants from me in the position. It's just great to be back.
“Some things have changed but most of the people are the same. It feels familiar and when I walked back into Cobham I felt at home straight away."
