"I loved everything about this club when I was here, and I still do," he told reporters.

"I would like to thank the Newcastle fans for the fantastic support they gave me while I was here, and for the reception they gave me on Sunday.
"Obviously I could not have asked to have gone to a better club than West Ham for the following we have got and the commitment they have shown, so I'm delighted to be at another wonderful club.
"Hopefully I can do as well for them as I did up here."
