The Red Devils found themselves eight points clear of cross-town rivals Manchester City in the run-in, but a dip in form saw Roberto Mancini’s men claim the title on the last day of the season.
The Serb has confirmed that he is back fit after a cruciate ligament injury and feels his players will be more determined to top the pile this term.
“We had some young players play a lot of games last season and they’ll have learned a lot. We all learned,” Vidic is quoted as saying in The Telegraph.
“In Europe we’ve had so much success in recent years – we’ve had three finals, a semi-final – and maybe we relaxed a bit last season.
“We were punished and we can’t allow that to happen again. We had a few injuries last season too. I hope everyone can stay fit this season.
“The young players can learn from last year, so I’m confident we’ll be better this year.
“You want hard games during pre-season. We want to be prepared as best we can for the first game against Everton.
“I think it’s important to have tough games before the beginning of the season and hopefully one of those will be Barcelona – actually, I know one of those will be Barcelona.
“But I think both us and Barcelona are concerned more with fitness and playing good football at this time of the season than we are with winning.
“Everything we’re doing is geared towards being ready for the start of the new season.
“For me, it was really good to have 60 minutes in Oslo. Hopefully I’ll play even longer against Barcelona and I should be fit for the beginning of the season,” he concluded.
