× Valerien Ismael has once again been left frustrated with a referee after Leigh Doughty did not give Barnsley a first half penalty in a 0-0 draw at Nottingham Forest on Saturday. Centre-back Michal Helik was clearly pulled down by Samba Sow in the 22nd minute, following on from Wednesday's 2-2 draw with Cardiff City in which referee Andy Woolmer gave the visitors a controversial corner which they scored from. Ismael called the performance of Doughty 'unacceptable at this level' and told the Chronicle: "I can't understand it. We have had two really really big game-changing mistakes in two games. It's enough, we need to have clear and proper decisions. It is a big big frustration that we only got a point.
