Manchester United have been inconsistent this season but star forward Cristiano Ronaldo says the club will need time to adapt, adding that they will get better if players know their role.
The Red Devils are sixth in the Premier League – five points off leaders Chelsea – and have taken just a point from their last three league games.
“We are in a moment in my opinion that Manchester [United] do a few changes,” Ronaldo told SkySports.
“They buy me, they buy [Raphael] Varane and [Jadon] Sancho.”
“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,” added Ronaldo.
“Everyone should know their role. I know my role in the team, in the club – my role is to score goals, to help the team with my experience and know-how to understand the game.
“If everyone is thinking like that, sacrifice for the team, I think we will be a better team.”
Ronaldo rejoined United in the summer from Juventus, while the club also signed defender Varane from Real Madrid and winger Sancho from Borussia Dortmund.
The great Portuguese has six goals in eight appearances for United and, despite being questioned over his work-rate, Ronaldo says he is not bothered about that.
“Criticism is always part of the business,” he added. “I’m not worried about that. And I see it as a good thing to be honest.
“If they worry about me or they speak about me, it’s because they know my potential and value in football still.”
