David Moyes gets soaked

The picture millions of Manchester United supporters have been waiting to see - a shocked David Moyes screaming after having a bucket of ice dumped on his head.

Moyes, who was sacked in April after a woeful 10 months at Old Trafford, was nominated by Marouane Fellaini, who he brought to United for £27.5m. It has not proved to be a smart piece of business - he has yet to score for United in a competitive match.

The Scot's anguish was for a good cause, however. He was taking part iin the Ice Bucket challenge, which raises money and awareness for amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease.

Those involved in the challenge can either choose to have a bucket of ice and water poured over them within 24 hours of being nominated, or write out a cheque for $100 to a ALS charity of choice.

Moyes joins other managers Sam Allardyce and Jose Mourinho in taking the challenge.

Harry Redknapp, on the other hand, will not be needing to take part. He has already had a bucket of ice publicly thrown over him. Remember David Bentley's jape from 2010?

And Arsene Wenger could be next - Robert Pires has nominated him.
