Manchester United manager Louis van Gaal believes the 1-0 win at arch-rivals Liverpool can re-ignite their Barclays Premier League title challenge.
Wayne Rooney’s 78th-minute strike – the visitors’ only shot on target at Anfield – settled a game low on quality and chances.
It left United within seven points of leaders Arsenal and Van Gaal has not ruled out a late charge for the summit.
“We have a lot of matches still to go,” said the Dutchman.
“We started 2016 very good with a lot of wins and I think this game will give a big boost to the players and the fans, and everyone in the environment of Manchester United.
“We have to continue, which is not so easy. We have seen that today but we can do it because we show every week we can do it.”
Asked whether it was his best day of the season, Van Gaal added: “No, I don’t think so. You have to see it always in perspective.
“It is a fantastic win for the fans, for me and the players and it will give us a boost, and maybe in that perspective you are right.
“There are matches we have played much better than today, and in that perspective I can’t say it is a good day because Liverpool were the better team in the first half and normally we are dominating games.
“I have to admit we survived the first half because Liverpool were more aggressive, we could not create anything.
“They have created in the first half three chances and that was surviving, but to beat Liverpool is always important.
“When I see this game then I think we can still improve but it was still good enough to win at Liverpool away.”
