Ole Gunnar Solskjaer beamed from ear to ear after enjoying a dream start to life back at Manchester United - and the caretaker manager warned the best is yet to come after hitting five past former club Cardiff.

Jose Mourinho paid for United's lack of style, substance and togetherness on Tuesday, with his Old Trafford reign brought to an abrupt end as the club turned to one of their treble-winning heroes for the rest of the season.

Solskjaer took charge for the first time on Saturday evening and not only got off to a winning start but oversaw United's first five-goal haul in a Premier League match since Sir Alex Ferguson's last game in May 2013.

Jesse Lingard's second-half brace complemented earlier efforts from Marcus Rashford, Ander Herrera and Anthony Martial as United won 5-1, with Victor Camarasa's penalty a mere consolation for Cardiff.

Asked if there were any positives, Solskjaer laughed and said: "There's quite a few!

"The attitude and application of the boys when you go out there and see them, the attitude has been fantastic, the dressing room, the way they approached this game.

"It's been a difficult week for everyone and to get the focus and perform as well as they did impress."

Solskjaer praised his team from front to back in the Welsh capital and playfully pointed out that this was returning coach Mike Phelan's first match in the dugout since United netted five in the league 2,043 days earlier.

The team certainly had a Ferguson era swagger about them, with Paul Pogba - one of four changes to the Liverpool loss - impressing behind the visitors' rapid attacking trio.

"I'm pleased with all of them - every single one of them - but of course it's a threat," Solskjaer said.

"When you've got Martial and Jesse Lingard down either side, Rashford up top with Paul supporting them, it's exhilarating to watch and as long as we keep that standard up we'll keep up picking points."
