Spurs were beaten 5-0 at home by Liverpool on Sunday which led to the sacking of Andre Villas-Boas and now interim boss Sherwood is hoping the north London club can hit back when they host the Hammers in the league cup quarter-final.
"When you lose your manager, it's a change and you've got to listen to a different voice, but I'm hoping to get a few messages across in a short space of time so we can get a positive result against West Ham," Sherwood told Spurs TV.
"It's a huge game, especially on the back of what they did to us at the Lane. It was disappointing.
"We have to get out there on the front foot and we have to impose ourselves on them as soon as we can during the game."
Sherwood added: "Hopefully they've (West Ham) got their concentration on Premier League safety rather than the cup tomorrow night.
"We have to be patient. They got bodies behind the ball and tried to catch us on the counter-attack.
"We're aware of that. Let's just hope we can impose ourselves on them nice and early, get the crowd behind us and really be up and at them."
