Manchester United legend Bryan Robson says the imminent arrival of Antonio Valencia from Wigan Athletic won't be enough to replace Cristiano Ronaldo.
Robson said: "The one thing everyone has to realise is that United are not going to replace Ronaldo. He's a one-off.
"Valencia is a good winger but he's not going to score the goals Ronaldo did. It wouldn't surprise me if the boss brought in another winger, even if he got Valencia.
"That would leave Wayne Rooney free to play down the middle. In fact, I can see Wayne and Dimitar Berbatov coming out of Ronaldo's shadow."
