Even if those dramatic five minutes of injury-time at the Etihad Stadium had not gone against his team on Sunday and United had been crowned champions for the 20th time, Ferguson would still have been plotting to improve his squad.
And no matter who eventually arrives at Old Trafford, Evra is certain Ferguson will get it right, saying: "Fans will want to see a few new players and I trust totally in the boss. He will do the right thing. There aren't many players who can play for Manchester United and I know the boss will make the best decision."
The real question is how good is this current United squad.
Some believe that, after collecting 89 points - the best achieved by any team finishing second in the Premier League era - there is not a lot wrong taking into account significant injuries to Nemanja Vidic and Darren Fletcher.
Others feel a continued reliance on Ryan Giggs and Paul Scholes, whose retirement U-turn triggered the surge in form that only six games from the end of the season looked certain to secure yet another title, is masking clear deficiencies and that the only surprise about this campaign is that United got so close.
Typically, Evra's glass is half full, accepting that the Red Devils are judged by exacting standards compared to the rest.
"Every year people criticise United. People say we've had the worst season ever if we don't win the league," he said. "This is not the truth. The season we've just finished has been a miracle. People were saying it was going to be the worst season but we are nine points better off than last year and we've scored more goals.
"We only think we've failed because we haven't won. Winning is the Manchester United spirit, it's the Manchester United way. It doesn't matter if you've only got one leg, you have to win.
"If I played for another team then maybe we'd say well done for coming second."
