Paul Scholes believes Cristiano Ronaldo is a problem for Portugal due to his age and limited mobility.
## What happened?
Ronaldo's sixth World Cup campaign started with a draw against DR Congo, with Scholes questioning his inclusion.
Scholes thinks Ronaldo's age is a significant issue, saying only a goalkeeper should start at 41.
## The Messi and Mbappe factor
Lionel Messi's hat-trick and Kylian Mbappe's brace will be frustrating for Ronaldo, according to Scholes.
Ronaldo failed to record a shot or successful duel in the first half against DR Congo.
## Tactical limitations
Scholes argues Ronaldo's movement is a problem in transition games, and he should only play the last 15 minutes.
Portugal needs a centre-forward who can run, but Ronaldo is not that player at 41.
Roberto Martinez defended his decision to keep Ronaldo on the pitch, citing his clinical nature in front of goal.
Martinez said the experience of Cristiano in the box is important, and he attracts defenders.
## What comes next?
Ronaldo will likely start Portugal's next group game against Uzbekistan, despite Scholes' criticism.
Scholes feels sorry for Martinez, who is trying to make the most of Ronaldo's abilities.
Ronaldo's anonymous performance against DR Congo has raised questions about his role in the team.
The former England midfielder thinks Ronaldo's ego will be hurt by Messi's hat-trick.
Ronaldo's age and limitations are a challenge for Portugal, and Scholes believes it's affecting the team's performance.
