Chelsea boss Graham Potter admits the club's ambitions are a lot higher than his previous jobs.
The former Brighton coach has never managed a side that is contending for trophies.
He spoke about his previous spells at Ostersunds, Swansea, and Brighton, and how they can prepare him for the challenges that lie ahead at Chelsea.
Potter said during a news conference: "I've spent seven years at Ostersunds, a year at Swansea where we pretty much had to sell everybody and be creative with who we were using, at Brighton obviously three and a bit years there.
“It's a different model, so you have to take the experiences, take the things you learnt in that context and apply them here even though it is different, like you say, totally.
“It would be wrong of me to think I'm in Brighton or back at Ostersunds, we're at Chelsea, the numbers are different, the ambition is different in terms of where we're trying to get to."
