Stoke 0-0 West Brom: Albion should have won - Steve Clarke

West Brom boss Steve Clarke believes his side "should have won" their goalless Premier League draw at Stoke, claiming a "stonewall" penalty was denied.

The Scot thought Charlie Adam "stepped on the back" of Youssouf Mulumbu's ankle in the second half - a claim turned down by referee Howard Webb.

The draw extended the Baggies' unbeaten Premier League run to five matches.
