Chelsea boss Graham Potter admits that adjusting to many changes at the club has not been easy.
The former Brighton coach was thrust into the job with the season already started, replacing Thomas Tuchel.
Since then, Chelsea have secured significant signings in the winter, but Potter acknowledges that getting everyone to settle into the club is a challenge.
He told reporters during a news conference: "I think it's been tough for everybody because there was change in the summer, there's been change previously to that, there's been a 20 year ownership which has moved on and a different one's come in.
“Loads of things have happened that make it suboptimal. Let's say that. But if I wanted a nice, easy life then I would have stayed at previous employments. The point of this opportunity was the challenge of trying to shape and help and support a football club in quite significant transition. That's what it is.
“What we've done in this window is exciting, the players that we've got are exciting, you can see the direction we're trying to go in which is building for the future but at the same time quality that can compete now.
“I think it's, and I'm going to use the word again, it's exciting times for me. As much as the manual might say something different, things are never perfect and you just have to make the best of it.
“My job is to help the club get better and constantly improve and when you look back on all my time on all my jobs, when I have left the football clubs they have all been in a better place than from when I arrived. That's essentially the job of a head coach, to help the club, support the club, improve the club and improve the team. And take on the challenge."
