Watch United at Boro on Sky Sports 1 on Sunday from 1pm
Wayne Rooney is confident Manchester United will win the Premier League, if they stay unbeaten in their remaining six games.
United can restore their lead at the top of the table to five points on Sunday with victory at Middlesbrough, live on Sky Sports 1.
The reigning champions are on a six-match winning streak in the league and Rooney has praised the defence for conceding just 15 goals.
And Rooney, whose only defeat in a United shirt this season was against Portsmouth in the FA Cup, feels United can retain their title.
"If we can go through to the end of the season unbeaten in the league we have a great chance of winning it," said Rooney in the News of the World.
"The most important thing for me is to win things for the team. I am not really too concerned about that unbeaten personal record to be honest.
"We are doing very well at the minute. The defence has been brilliant all season. If they carry on keeping clean sheets, I am sure us front players will keep winning the games."
Rooney has scored 16 goals for United this season, but insists he was never seriously concerned when he experienced the occasional drought.
He added: "I have missed more games this season with a couple of injuries than I ever have since I joined the club. I would not have wanted to miss those games, but it will help as we come to the end of the season.
"I was a little bit worried, but not too much, when I went through a couple of lean spells, but we were playing well and winning games, so it wasn't really a major concern.
"As a forward you always want to score, so I was delighted to get a couple of goals against Aston Villa last week and in Rome the other night.
"I am not too sure about how much I've improved as a player. I will let other people decide on that. I think the team has improved a lot and I just try and do my best for the team.
"Is there a lot more to come from me as a player? I hope so, yeah. I want to try and get better and make myself a better player. I want to try to do that.
"I have scored a few more goals this season from inside the six-yard box. It was good for me to get one like that against Roma. A goal is a goal. It doesn't matter where they go in from."
