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.
United require a point from their final two games against Blackburn and Blackpool to snuff out any remaining hope.
Only then will Vidic start popping the champagne corks.
"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.
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.
However, Wayne Rooney has escaped any sanction for a gesture some claimed was aimed at the Chelsea fans but he argued was actually towards the assistant referee and was a rather blunt request for the official to use his eyes.
