Manchester United's Anderson scores against Tottenham Hotspur during their English Premier League match in Manchester.

Danny Welbeck was in impressive form for Manchester United as the defending champions beat Tottenham Hotspur 3-0 at Old Trafford on Monday night.

Manager Sir Alex Ferguson's decision to field a starting XI with an average age of just 23 was justified after an hour of Tottenham resistance when 20-year-old forward Welbeck glanced a pinpoint cross from midfielder Tom Cleverley past goalkeeper Brad Friedel to give the hosts the lead.

Spurs manager Harry Redknapp was without the unsettled Luka Modric, with the playmaker the subject of a £30m bid from Chelsea - and the 24-year-old Croatian was badly missed as United dominated the Spurs midfield after an evenly-fought first-half.

Anderson doubled United's lead in the 76th minute, after Welbeck's clever back-heel set up the Brazilian and Wayne Rooney sealed the home side's victory with a late header to continue their perfect start to the season following last weekend's win at West Bromwich Albion.

"The second half we just took off," Ferguson told Sky Sports. "It tells you we still believe in young players ... more so when you see the ability they've got.

"The second half performance was absolutely fantastic; I thought it was a really fast game in the first half - end to end."
