Dimitar Berbatov admits he's unhappy with his form at Tottenham.
"When you don't score it's frustrating. But if I don't and others do and we win, as we did against Middlesbrough in midweek in the Carling Cup, then that's the important thing. That is when everyone is happy."
Spurs believe that Berbatov will soon make opponents pay for his frustration - hopefully starting against Aston Villa at White Hart Lane tomorrow night.
He also told the Mail on Sunday: "I cannot give a reason for my form, not exactly. Maybe the defenders know me better. But I have to say if they think that's the cause, then it shouldn't be.
"Last year was very good for me and, yes, it has become more difficult. But it's not an excuse and I try to work even harder. I will keep pushing until I score again.
"It's depressing when you lose, but when that happens you must keep your head up and keep working hard."
