Tottenham boss Redknapp: Derby victory ideal going into Werder Bremen clash
Redknapp is hoping his side carry the euphoria from that victory into Wednesday's match.
"Knowing what it means to everybody associated with this club - the fans, the players, everybody who follows the club - to go to the Emirates and win as we did at the weekend must give us great confidence," he said.
"Hopefully, we can carry that through tomorrow night and really make it a springboard from here to push on for the rest of the season."
On Wednesday night Tottenham play the penultimate match of what has been a rollercoaster of a Group A campaign.
Victory would ensure they would go into their final game at FC Twente already qualified, which would be no mean feat in what has been their maiden season in the Champions League.
Reiterating it was still "all to play for" in the group, Redknapp said: "It would be a great achievement.
"One or two of the groups, you look at them and there are a few games that are almost 'gimme' games. But, in this group, it was always going to be difficult."
