Rafael van der Vaart has said that Tottenham Hotspur were not at their best, despite beating Watford 1-0 in the FA Cup last night.
The Dutchman's first-half strike was enough to send Spurs into the fifth round of the competition after what he described as a "difficult game" at Vicarage Road against the Hornets.
"I think we played a bad game," he told ESPN. "Sometimes you have these days. The 100% sharpness is not there.
"I think it was a difficult game, the pitch was heavy and yes they played a great game.
"It was a lucky strike but I'm happy it caused the win."
Meanwhile, Tottenham boss Harry Redknapp has echoed his playmaker's sentiments.
