Manager Louis van Gaal says Manchester United have to complete a hat-trick of victories as they prepare to face West Ham United on Sunday.
The Red Devils eased past Leicester City and Cambridge United in their last two games and the Dutchman says it is vital to take all three points from the Boleyn Ground.
"I said that at the beginning of the week before the game against Leicester City, that this is an important week and we have to win all three matches," van Gaal told MUTV.
"After we beat Leicester we were third in the league. After that, we beat Cambridge and we are in the next round of the FA Cup.
"Now, we have to continue and all of the players know that it's true, but it's not so easy because we have to play away in London against West Ham and it was a tough game in Manchester.
"It shall not be easy, but we want to continue. We have to win in London.
"We are fourth in the goalscoring league and third or fourth in the defensive way of playing [goals conceded]. I don't think we are very bad - we are very good but we can improve."
Meanwhile, the Dutchman confirmed midfielder Michael Carrick is the only injury concern ahead of the game.
"We have only one injury and he [Michael Carrick] is doing well," van Gaal explained.
"He shall also return very fast I think, better than we expect maybe, but it is always [a] wait and see [situation]."
