Just before Barnsley scored, when the Birmingham player kicks his leg out and that leg hits Cotterill's standing leg, thats called a foul and also a 'penalty'. Hope this helps you in future games. No thanks necessary.
Let's also include the linesman on East Stand side who gave Done off-side when he was clearly on-side AND didn't have the b0ll0x to give the penalty. Very poor.....both of 'em.
