From where I sat Barnsley were, if not running riot, certainly having the better of things down both our left and right, and for large chunks of the game. Playing 3 in midfield plus Weimann made us really unbalanced, and (this might be unpopular) Bakinson and HNM seemed to be leaving large gaps behind them. So whether young Ayman or anybody else came on the structure was wrong.
Big call by Pearson, mind.
