The striker has happy memories of facing Spurs, having scored the first goal in Portsmouth's 2-0 FA Cup victory over them last season.
"We progress with each game and Tuesday night against Sunderland was the best because we won and we played very well," he told the London Evening Standard. "Before that we had played well enough but had missed some chances.
"Now the team have come together. It takes time but against Sunderland everything seemed to work and we scored the goals we had been threatening in previous matches.
"Tomorrow is a really important match for us - a crossroads, if you like - for everybody, because Tottenham are a very good team and we want to see how much we have improved in recent matches. If we all do the maximum, we can win this game."
