The Red Devils picked up 19 points from their opening seven games in the Premier League after an impressive return of 21 goals and six clean sheets to lay down an early marker in the title race.
Manchester United travelled to Anfield and adopted a negative approach to secure a goalless draw with bitter rivals Liverpool last weekend.
Mourinho’s side were criticised for showing a lack of adventure against a Liverpool defence that went on to conceded four goals in a 4-1 loss to Tottenham Hotspur on Sunday afternoon.
Manchester United lost further ground on Premier League leaders Manchester City on Saturday following a 2-1 loss to promoted side Huddersfield Town at the John Smith Stadium.
The Red Devils are five points behind leaders Manchester City but level on points with third place Tottenham ahead of their clash at Old Trafford next weekend.
Former Arsenal striker Henry believes it is too early to write off Manchester United in the title race this season.
“We will get our answer next weekend,” Henry told Sky Sports.
“Don’t write Man United off yet, it’s still early.”
Manchester United finished in sixth place in the Premier League table last season but won the League Cup and the Europa League.
