Ole Gunnar Solskjaer says there is no chance his players can think they have "cracked it" if Manchester United go top of the Premier League with a positive result against Burnley.
After a truncated pre-season and shaky start to the campaign, the Red Devils head to Turf Moor on Tuesday night level on 33 points with reigning champions and bitter rivals Liverpool.
A positive result in that game in hand will see them move top ahead of Sunday's mouth-watering trip to Anfield, but Solskjaer knows a thing or two about winning titles and will not allow the group to get ahead of themselves.
"We have to be aggressive," said the Norwegian, who was part of six Premier League-winning sides during his time as a player at Old Trafford.
"I think that the signings we made in the summer strengthened the squad really well," the Norwegian said. "Good signings, good characters, good players.
"January's always difficult but if something comes up that you think about in the long term, it's a long-term target anyway, that's another scenario.
"But not many teams would like to lose their players in January, so unlikely something will happen on the in side.
"There might be two or three going out because they deserve to play more football for their own good and their own career."
