Sunderland boss Gus Poyet says he doubts Chelsea have an unbeaten season in mind as Jose Mourinho's men prepare to head to the Stadium of Light on Saturday.
The all-conquering nature of the Londoners' start to the season has raised inevitable comparisons with Arsene Wenger's 'Invincibles' who finished the 2003/4 season without a loss.
But Poyet believes that while the prize of becoming the first team to beat them is there for opponents, Mourinho will have different priorities.
Poyet said: "There are plenty of games to go and I don't believe the aim for Chelsea right now is to not lose a game.
"I think it is to win every trophy and if they need to lose one or two games I don't think they are going to be too bothered about it."
Poyet masterminded his side's win at Stamford Bridge in April which shattered Chelsea's 77-game unbeaten home record, and also overturned them in the Capital One Cup.
Poyet added: "If you win every game you get stronger and you get that feeling in the team that you can play badly and still win and at least get a draw.
"But the next team is the one who has the opportunity to stop them somehow and everybody is going to want to take that chance - and now the opportunity is for us."
Meanwhile Poyet confirmed Argentinian wide man Ricky Alvarez could feature after recovering from an injury which has kept him out since the end of September.
