Manchester United forward Cristiano Ronaldo believes the Old Trafford side need time to adapt.
It comes after an inconsistent start to the season.
United are sixth in the Premier League and five points off leaders Chelsea.
The have collected just one point from their last three top-flight games.
They host Liverpool on Sunday, with their rivals second on 18 points.
“We are in a moment in my opinion that Manchester United do a few changes,” said 36-year-old Ronaldo.
“They buy me, they buy Raphael Varane and Jadon Sancho.”
Portugal international Ronaldo rejoined the club in the summer after a move from Juventus.
United signed defender Varane from Real Madrid and winger Sancho from Borussia Dortmund.
“The adaptation will take time, even the system of the game that we play.”
“But I think step by step we have to put it in our mind that everything is possible,” Ronaldo added.
“Everyone should know their role.”
“I know my role in the team, in the club – my role is to score goals.”
“And to help the team with my experience and knowhow to understand the game.”
“If everyone is thinking like that, sacrifice for the team, I think we will be a better team.”
Ronaldo scored the winner for United after they came back from 2-0 down to beat Atalanta in a Champions League group game in midweek.
