Ledley King has admitted that Tottenham Hotspur must learn from their defensive errors against Manchester United yesterday afternoon.
Despite dominating large parts of the match at White Hart Lane, Spurs ended the match empty-handed following a 3-1 loss.
Captain King believes that individual errors were the difference between the two sides.
"It's tough to take because I thought for the majority of the game we gave a good account of ourselves," King told the club's official website. "But if you fall asleep at vital times you will get punished.
"You won't beat teams like United unless you are fully concentrated for the full 90 minutes, and that was a bit of a lesson.
"You can't fault our work-rate but it's those moments that make all the difference."
The defeat means that Spurs remain third in the Premier League table.
