Roy Keane believes Cristiano Ronaldo can use Thursday's meeting with Ghana to 'shut a few idiots up' after facing criticism in recent weeks for his conduct at Manchester United.
The former United skipper suggested Ronaldo can let his football do the talking in the week that saw him leave Old Trafford with immediate effect.
The 37-year-old gave a now-infamous interview to Piers Morgan, in which he blasted numerous figures at the club and admitted he felt betrayed by United.
He will lead the line for his country as they take on Otto Addo's Black Stars in their opening World Cup game in Qatar.
