Cape Town - Manchester United Ander Herrera said that Manchester United’s rivals should be worried by their recent form.
Jose Mourinho’s Red Devils are currently on a 15-game unbeaten streak in the Premier League and sit sixth in the league, just five points behind second-placed Tottenham.
United moved to within two points of the top four following last week’s 3-0 win over Leicester, and the Spain international believes the team is building momentum.
Asked if teams surrounding United should be worried, Herrera replied: "That's what we want."
"I think the fight with the first six teams in the league - and I add also Everton because they have a very good team - will be very tough.
"We all want to be in the top four and there's still a lot play for, but I think we are in a good moment. They can see 'Man United is chasing us'.
"It is true that we did not win three games in a row before Leicester, but the feelings were good. I think we deserved more away at Stoke and against Hull at home, so I think we are in a good moment.
"We are fighting for a lot of things. Three competitions plus the Premier League, the race for the top four. I think we have a lot of things to play for. All the players in the squad want to play as many games as possible."
United have finished 7th, 4th and 5th in the Premier League since Sir Alex Ferguson retired in 2013, with last season's FA Cup the only major trophy.
"We didn't finish higher because we didn't deserve to finish higher," said Herrera, who added that United aim to do better this season.
"I think football, sooner or later, is fair. Now I think we look stronger. People can see that."
United next face Watford at Old Trafford on Saturday with Mourinho hoping to close the gap to the Champions League spots with Liverpool and Tottenham Hotspur going head-to-head over the weekend.
Kick off is at 17:00.
