Evergreen, Paul Scholes marked his 700th Manchester United appearance by sending the Red Devils to their biggest win of the season after victory over Wigan at Old Trafford.
Sir Alex Ferguson described Scholes' cameo at Southampton last month as like someone 'opening a door'.
Mixing a typically astute performance with some of those thunderous challengers for which he is noted, Scholes also broke the deadlock with his 155th United goal.
Few could have been converted in such ease as he tapped home after Ali Al Habsi had pushed Nani's low cross straight into his path.
Javier Hernandez, who missed a first-half penalty, bagged a second when he turned home Alexander Buttner's misdirected shot, then the Dutchman capped a fine debut by driving home the hosts' third, putting more pressure on an underperforming Patrice Evra, who watched from the stand.
Robin van Persie was introduced 19 minutes from time but it was his fellow substitute Nick Powell who wrapped up the win on his debut, blasting in from 20 yards.
Although he declared Van Persie and Shinji Kagawa fit on Friday, Ferguson opted to leave both men on the bench as he cast an eye towards the start of his side's Champions League campaign against Galatasaray on Wednesday.
With veteran duo Ryan Giggs - making his 600th Premier League appearance - and Scholes flitting in and out of the game and Alexander Buttner looking dangerous on his debut, the hosts carved out a succession of opportunities.
