Nemanja Vidic will only allow Manchester United to start their title party when he knows it is impossible for Chelsea to wreck it.
Although Carlo Ancelotti's men have little chance of overhauling the Red Devils following Sunday's defeat at Old Trafford, mathematically it is still possible. United require a point from their final two games against Blackburn and Blackpool and Vidic is not taking anything for granted.
"We will only start to celebrate when we have the trophy," said the United skipper. "A big part of the job is done but it is not finished. We still have to perform at Blackburn."
Vidic does not need any reminding that Ewood Park was where United surrendered their crown last term.
Coming in the wake of their Champions League defeat to Bayern Munich, a goalless draw turned the Red Devils' dressing room into a morgue.
The difference could not be more marked if United were to match that result this time around, confirming, as it would, a record 19th league championship.
Not that Vidic has any intention of settling for such a result.
"A draw would be enough but Manchester United do not play like that," he said. "We always try to win and Saturday will be no different.
"We know Blackburn are a good side on their own ground. We drew there last year. They are a strong, so we will have one week to prepare if we are to win the league."
