Early exits from the Champions League and Carling Cup have provoked a surge in the Reds' Barclays Premier League form, while October's Manchester derby setback met with a similarly positive response.
"We’ve lost three games this season, and in a normal season by December you could possibly have lost three games, but the ones we’ve lost were very difficult for us," Sir Alex told his pre-Blackburn press conference.
"It’s difficult for a club like Manchester United to handle a 6-1 defeat by City, but we recovered. Crystal Palace? We recovered. Basel? We recovered. It tells you something about this team, and eventually their confidence and trust in each other comes through."
United welcome Blackburn to Old Trafford on New Year's Eve, having won five successive league games and plundered 17 goals, bearing out the manager's early-December prediction that they would bloom in spectacular fashion.
"We’re seeing some terrific attacking play at the moment," he said. "Hopefully we can keep the momentum going. The players are enjoying themselves too and playing with good confidence now. I said a few weeks ago someone was going to suffer and that’s what’s happening now."
