Barnsley manager Simon Davey is overwhelmed after his side caused a major upset in the FA Cup, defeating holders Chelsea 1-0 in the quarter-finals. The Championship side deserved the Giant Killer tag after producing astounding victories over Liverpool and Chelsea. "We have beaten Chelsea here. It is a magnificent achievement. The players deserve everything that is going to come their way after this,” the Barnsley coach told the club's official site. Kayode Odejayi's header sent the Tykes to the FA Cup semis for the first time in almost a century. "There were last ditch tackles and last ditch saves. Kayode was magnificent out there. He is not the only hero because everybody deserves credit. "It is like a dream and we are going to Wembley. I have never been there before and it is what dreams are made of. It has not sunk in," added Davey.
