Chelsea defender Branislav Ivanovic believes the fixture against Manchester United gives the Blues an early chance to stamp their authority on the Premier League title race.
Ivanovic is keen to get off to a flying start following the return of Jose Mourinho and he already has his eyes on the trip to Old Trafford on August 26.
He said: "It's very important, more mentally, because it's the beginning of the season.
"That game will not decide who is going to be champions, but it will decide a lot of things about the confidence and about the team.
"It's very important for us psychologically to start the season well. I think it can give us extra confidence and after that we can play game by game.
"The season is very long. We have to be ready for every challenge."
