Nemanja Vidic has praised German duo Bayern Munich and Borussia Dortmund following their progression to the UEFA Champions League final.
Dortmund edged past Real Madrid to seal their place in the Wembley showpiece, while Bayern sent shockwaves around Europe with their 7-0 aggregate demolition of Barcelona in the last four.
And Vidic believes both teams fully deserve to have progressed to the final after some high-octane showings, hinting that United should adopt a similar approach to ensure success in Europe.
"Credit to Bayern. I think they play very good football," he told MUTV.
"They play as a team and they closed down the Barcelona players very quickly, going in groups. It's hard to play against these kind of teams.
"Dortmund played against Madrid in a similar way to show this is the tendency in Germany football.
"I think it's something we should look at. Maybe this is the way other teams have to improve. Over a few years, people were watching Barcelona and saying this is how you should play.
"If you look at Dortmund and Bayern now, you see that they work as a team and individuals and this is why they are having success."
The Serbia international went on to bemoan his side's failure to progress beyond the last 16 in this season's competition, but suggested Sir Alex Ferguson's men had still enjoyed a successful season.
"It's hard to watch these kind of games as you know maybe we could be there," he added.
"But I think, at the end of the day, we should be satisfied with our season. We won the title, which was our priority this season, but we he hoped to do better in the FA Cup and Champions League.
"But this is life, this is football. Sometimes you lose, sometimes you win."
