West Ham United won't consider offers for England centre-back Matthew Upson.

The Telegraph says Arsenal are believed to be among the clubs interested in Upson, who has started each of England's last three matches, but West Ham remain adamant that the financial difficulties of owner Bjorgolfur Gudmundsson will not force unwanted player sales next month.

Upson is regarded as integral to manager Gianfranco Zola's long-term plans, though the Italian is preparing to significantly reduce the size of the squad over the next six weeks.
