Manchester United boss Jose Mourinho has warned fans not to get carried away with their run of victories.
United meet Wolves on the back of three consecutive wins today.
"For sure, a difficult season," said the United manager ahead of Saturday's clash at Old Trafford.
"I don't change that because we won two matches in the Premier League.
"You see the level of the teams. You see the Liverpool squad, (Manchester) City squad, Chelsea squad, Tottenham squad, Arsenal improving. It's going to be difficult.
"I'm not saying we are going to have more points than last season because last season we collected a very acceptable level of points.
"I think we are going to be a better team. We are going to play better than we did, but I think it's going to be a very difficult season.
"I am optimistic, but a difficult season, yes."
