Manchester United forward Cristiano Ronaldo believes the Old Trafford side need time to adapt after an inconsistent start to the season.
United are sixth in the Premier League and five points off leaders Chelsea after collecting just one point from their last three top-flight games.
They host rivals 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, while United signed defender Varane from Real Madrid and winger Sancho from Borussia Dortmund.
