Chelsea boss Graham Potter says facing Manchester United tonight will be a good test for where the team is under his management.
The Blues host United later tonight.
"It's a really important game for us, an exciting game and one we're really looking forward to," admitted Potter. "Because of the opponent. it will give us a good piece of information in terms of where we're at and where we need to go.
"That's part of the process we have to go through so in that regard we're really looking forward to it. We've picked up points in the Premier League and there have been lots of positives but there is still lots to do to improve as well. It's exciting but we'll be tested."
Potter has already orchestrated a victory over Erk Ten Hag's United this season while Brighton boss.
"They've changed a little bit in terms of how they build up, a bit more direct and longer balls, but at the same time they still have the same quality with the threats of [Marcus] Rashford, Antony, and [Jadon] Sancho," he explained.
"Bruno Fernandes plays a key role for them so there's a lot of similarities but they just seem to have adapted to the competition and to each other, probably learning more about each other.
"I'd been at Brighton for three years when we played and Erik had been at Man United for six weeks so there's a lot of learning you need to do and a process you need to go through, which is normal really. They have the quality so it's natural they will get better and better as time goes on."
