Harry Redknapp has shrugged aside any suggestion that physical and mental tiredness might be a factor against Arsenal after Sunday's defeat at Wembley.
We take on the Gunners tomorrow night (Wednesday, April 14, 8pm) just three days after playing extra time in a devastating 2-0 defeat to Portsmouth in the semi-final of the FA Cup.
It's one of the most important North London derbies of recent seasons as we challenge for fourth place in the Barclays Premier League and Arsenal still fight for the title.
Asked how much Sunday's defeat and 120 minutes at Wembley could be a factor, Harry insisted: "This is a London derby and we'll find the energy.
"We did it last year. We played United in the Carling Cup Final on the Sunday, it went to extra time and penalties and we came back and played Middlesbrough on the Tuesday night and won 5-1.
"We'll be okay. There are no excuses and we'll be ready to play.
"These matches are always significant. Tottenham against Arsenal is always a massive game for both sets of fans and it's a game we want to win.
"It will be a tough game. They are a tough side and they are going well, but we're in great form as well. We had five straight wins in the league before Sunderland.
"We had one of those days against Portsmouth on Sunday. It didn't go our way. That's history and there is nothing we can do about it now. You put it behind you and move on again.
"That's what you do. You pick yourself up, brush yourself down and start all over again. You can't look back - what happened last week, happened last week. It's what happens tomorrow that matters now.
"It's another day, another game - a London derby. The adrenaline will carry the players through whether they are tired or not. We're ready for a big game."
