Ander Herrera hopes Manchester United's "very bad week" was just a blip after ending a losing run with a timely victory at Northampton Town.
Jose Mourinho's side avoided a fourth straight loss in all competitions after beating Northampton 3-1 on Wednesday, with Michael Carrick, Herrera and Marcus Rashford securing a 3-1 return to winning ways at Northampton.
"When you play these kind of games, people don't realise how difficult it is," the Spanish midfielder told beIN SPORTS of facing their League One opponents.
"Now we are going to think about keep winning games. We want to think it was a very bad week and now we can face Leicester in a different way, more positive.
"Hopefully we can win and we can keep being in the high [parts] of the table."
A clash with Pep Guardiola's City now awaits in the fourth round, but Herrera is more interested in the positive impact Wednesday's win can have for reigning champions Leicester's visit at the weekend.
Herrera was one of the nine United changes at Sixfields and staked his claim for a regular starting berth with a solid display, striking the post from distance before finding the net with a thunderous effort.
"I try to shoot when I can play, when I can help the team," he said. "I could score another goal before but I am very happy because when you score you can help the team more.
"I know my role, I know what I can give to the team, but as a midfielder when you score of course you are helping more the team.
"We know we have controlled the game and when you control the game, that's when midfielders control the ball, control the game as well.
"We tried to play as quick as possible, one, two touches, I think the team needed that today because they were going to press a lot.
"We were not going to be able to drive too much the ball, so great victory and now we are facing in the next round Man City so it's very good for everyone.
"We still have, I think, six or seven games before that, so we will have time to think about it. But we have another chance to play against a top team and show what we are able to do.
"Overall, in front of our fans we couldn't win the last game against them so we have another chance."
