Birmingham - West Bromwich Albion manager Tony Pulis has backed under-fire goalkeeper Ben Foster ahead of his return to Aston Villa four days on from a costly error in the local derby.
Villa won Tuesday's league meeting with Albion in dramatic fashion after Foster gave away a last minute penalty when he needlessly fouled Matthew Lowton, with the spot kick converted by Christian Benteke.
England international Foster took to Twitter afterwards to apologise for his performance.
