Boss Jose Mourinho has hit out at the Premier League over Chelsea's fixtures.
He cited the fact that the Blues have to play away from home in the Premiership after each of their first five European outings next season.
And to add to his ire, rivals Arsenal have been handed five corresponding home fixtures on those weekends.
"It is always Chelsea who get the worst games, the worst fixtures to play, while Arsenal always have the best ones," he told The People newspaper.
Mourinho has also criticised the Football Association for the scheduling of their FA Cup fifth-round match away to Newcastle last season - a game they lost 1-0.
"That game didn't come at the right moment because we had to play Newcastle on Sunday and then Barcelona two days later," the Portuguese manager said in a special edition DVD review of Chelsea's title-winning season.
"Nobody anywhere else in Europe would believe this."
Following the arrival of Spanish full-back Asier del Horno, Mourinho added that he intends to sign two more players prior to the start of the new campaign.
"The most important thing is to keep what we have, in other words to retain the Premiership, and we have a squad powerful enough to do that," he stated.
"But we also have to change one or two players.
"In every group, in every squad, there are always one or two players not very happy with their personal situations.
"Of course they are happy with the success because they belong to the success but some of them are not very happy because they are not my first choice.
"So those are my key tasks - to keep what we have, bring in a left-back, a midfielder and an attacker and improve in every department of the squad.
"And our group will be even better next season, it's simple."
