Marcus Rashford wants Manchester United to guard against complacency and start afresh in their EFL Cup semifinal second leg away against Hull City on Thursday.
Jose Mourinho's side have a 2-0 advantage from the first leg, when goals from Juan Mata and Marouane Fellaini sealed the victory at Old Trafford.
United have already won at Hull this season, 1-0 in the Premier League back in August, when Rashford scored a dramatic, late winner.
When asked about guarding against complacency, Rashford told MUTV: "I do think that's the biggest thing that we've got to try to do. Leave the last game behind us because it's done.
"We're going to face new challenges when we play against them at Hull. They will have the home fans behind them and are going to be raring to go so I think it's important we keep our focus.
"I think if a goal goes for or against us, we must keep the same mentality -- to go out there to win every game. I think, if we concentrate on our own focus, then I'm confident we'll get the job done.
"I think Hull have begun to find the form they were showing at the start of the season again. They're defending well as a team and creating more chances as well."
The crowd at Hull will show their support for midfielder Ryan Mason, who suffered a fractured skull in the 2-0 defeat at Chelsea on Sunday.
Rashford said: "It's a terrible thing that's happened [to Ryan]. In a contact sport like football, things like that do happen and, of course, everyone is happy the news is better regarding a speedy recovery and we all hope he plays again soon."
