Life after Alex Ferguson continues to be jarring for the Old Trafford faithful, with this another turbulent campaign for the 20-time league champions.
Louis van Gaal's style of football has been widely criticised, yet his side enter the home straight with a chance of squeezing into the Champions League spots.
United's win at Manchester City before the international break was followed by a narrow victory over Everton, giving Herrera and his teammates confidence ahead of Sunday's trip to second-placed Spurs.
“I think it is an important moment of the season because we don’t have many games left,” the Spanish midfielder said.
“It’s good that we are in good form and we have to keep winning our games.
“It’ll be a great game. They are very strong and fighting for the title.
“Every player wants to play in this type of game and we will go to White Hart Lane to win.”
Recent history suggests Herrera has every reason to be confident, with United unbeaten in their last 14 Premier League trips to White Hart Lane.
Mauricio Pochettino’s second-placed side are a much better Spurs outfit than United have faced in recent years, but Van Gaal’s men have impressed against the better sides this term.
United have lost only one of seven matches played against fellow top-six clubs this term – a run they will look to improve in North London.
“I think we perform better against top teams and always give our best, and Spurs is one of those top teams,” Herrera told MUTV.
"I think Spurs and Leicester are the only teams that have been consistent.
"I watched Spurs' game at Liverpool, they controlled pretty much all of the game and played very well in the second half and could have won.
“They are still fighting for the title and we have to respect them because they have very good players.
“I think we have seen some surprises in the Premier League, this season and Dele Alli is one of them. Also I didn’t expect (Eric) Dier to play as well as he has done in midfield.
“Alli is a player who doesn’t need to touch the ball all the time. He waits for his moment and he has good timing into the box.
“He scores goals and assists often. The best way to defend against good players is by getting the ball.
“We have the capacity to do that, we have shown that against very good teams – we can beat them with the ball. That’s the best way to do it.
