Andre Villas-Boas has labelled Tottenham's performance in the 6-0 defeat to Manchester City as "embarrassing" and has apologised to supporters for such an abject display.

Spurs went behind after just 14 seconds when Jesus Navas expertly finished and it would go from bad to worse. Sandro put into his own net before a superb brace from Sergio Aguero was followed by a wonderful goal from Alvaro Negredo.

Navas would strike once again in the final minutes as Tottenham's defence simply fell apart, leaving Villas-Boas to reflect on a dreadful performance that sees his side slip down to ninth in the table.

"We're extremely disappointed." Villas-Boas told the club's official website. "It's difficult to find an explanation for a result like this.

"Everything went wrong for us, going from being one of the best defences in the country to suffering six goals in a fixture.

"The only positive we can look at is the 15, 20 minutes after the first goal, we reacted well, could have scored but didn't, and ended in a more difficult situation.

"It's an embarrassing defeat that all of us have to take. The only way we can react is by bouncing back in the next fixtures. The only thing I can say [to the fans] is sorry. It's a very poor result, not to our level."

Tottenham have now lost four games this season and face another difficult task this weekend when they host Manchester United at White Hart Lane.

United have had a difficult start to the season under new boss David Moyes but they haven't lost in their last six Premier League games and have started to come into some form.

Villas-Boas will be desperate for his attacking players to demonstrate their quality as Tottenham have now scored just nine goals in 12 games, despite spending close to £50m on Erik Lamela and Roberto Soldado.

The Spanish striker has scored just four league goals, while Lamela is yet to open his account in the Premier League and has seemingly struggled to adapt to the English game.
