Darren Fletcher admits United's win over Portsmouth could prove vital after the Reds moved three points clear of Liverpool in the Barclays Premier League title race.
Although the Reds also have a game in hand on both Liverpool and Chelsea, the Scottish midfielder is adamant that the reigning champions must retain a steely focus to get the job done.
"It was a massive result after Liverpool only getting a point against Arsenal," Fletcher told MUTV. "It was important that we came out and won. We’re top of the league, three points ahead and we have a game in hand.
"We’re not counting that game in hand because the points aren’t in the bag yet and there are going to be plenty of twists and turns in this season. All we can do is concentrate on ourselves and as long as we keep winning matches then we should win the league."
Tottenham are next up at Old Trafford before attentions switch to the Champions League visit of Arsenal, but Fletch says the players' thoughts haven't turned to the Gunners' mouth-watering visit just yet.
"We’ve got three massive home games," he said. "We got Portsmouth out of the way, now we look to Tottenham. We can only look to our next game and try and get three points in that. That’s always the case just now: concentrate on your next match and don’t get too far ahead of yourself."
