West Ham United goalkeeper Adrian has hit back at co-owner David Sullivan after he described new signing Joe Hart as the best that he has worked with.

Hart sealed a season-long loan move from Manchester City on Tuesday and is expected to become Slaven Bilic's number one.

The England international's arrival puts Adrian's future in doubt, with reports claiming that Newcastle United and Crystal Palace are considering a swoop.

After Sullivan's interview praising Hart was published, Adrian took to Twitter to give his response.

The Spaniard wrote: "Thanks for your sincerity! But you still having "two great professionals" respecting,fighting & defending this badge."
