Nemanja Vidic will only allow Manchester United to start their title party when he knows it is impossible for Chelsea to wreck it.
Although no-one believes Carlo Ancelotti's men have any chance of overhauling the Red Devils on goal difference following yesterday's defeat at Old Trafford, mathematically it is still possible.
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.
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."
Win or lose, United are condemned to finish the season with the least amount of away victories in any title triumph since Liverpool in 1977.
It is quite astonishing that alongside that record Sir Alex Ferguson's men boast home form that has seen them drop just two points - to West Brom in October - from 18 games so far, with just the visit of relegation-threatened Blackpool to come on the final day.
Such a vast disparity in performance explains why so many have been so sceptical for so long, much to the chagrin of Ferguson.
Vidic claims not to be bothered. However, he does declare any debate will be over should United wrap up that record 19th championship.
"No-one could say we were a bad team if we were to win a trophy," he said.
"Obviously, we listen to what people say but we don't think much about it. We just try to focus on ourselves.
"We know what our target is and we are nearly there. If we reach it, that will prove to everyone we are a good team."
Looking ahead to the Champions League final in three weeks, Ferguson does have some minor issues, with John O'Shea limping off yesterday, Darren Fletcher not involved even though the United boss intended to give the midfielder a 20-minute appearance and Patrice Evra ruled out by a thigh injury.
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.
It is a view the FA concurred with, meaning Rooney will be free to complete the season without any disciplinary worries.
Vidic will complete it as United skipper, having been trusted with the job by Ferguson, who felt he could not rely on the fitness of Rio Ferdinand whilst now-retired Gary Neville and evergreen Ryan Giggs were required to keep their focus solely on the games they were involved in.
The 29-year-old scored the all-important second yesterday, his fifth of the season, but his first since February 1.
It means he will have the honour of collecting the trophy after the home game with Blackpool on May 22, a prospect which he is finding difficult to put out of his mind completely.
"I am trying to be focussed as well but I am thinking about lifting the trophy as well," he conceded.
"To be the captain of Manchester United in this situation is a big honour."
