"It's fairly obvious the last few weeks at Manchester United were not a happy time for Ruud.
"But Ruud is extremely professional and I am sure he will be able to put those feelings aside.
"He wants to prove he is still one of the best strikers in the world, which is exactly what he is.
"I hope what has happened to Ruud at United will benefit us.
"Even in the recent friendly games, he has proved just how clinical he is.
"It is always great to have a guy like him in your squad, someone who can get you a goal out of nothing.
"He is looking very sharp, as are all our forward players.
"They are fast and skilful and they can get past defenders. It is going to be very hard for opponents to stop them."
