Glasgow head coach Sean Lineen bemoaned his side's "naivety" after their Heineken Cup chances suffered another blow with a 22-14 defeat at Newport Gwent Dragons.
Adam Jones, Luke Charteris and Martyn Thomas all crossed for the Welsh side in the opening half to leave Glasgow bottom of Pool Two following last weekend’s home defeat by Biarritz.
Warriors have just one point after a late Dan Parks penalty miss cost them at least a losing bonus point.
“We lost the game again and the Dragons didn't win it,” Lineen said. “They scored all three tries from us having the ball. “There was a lot of naivety from us and a lack of direction.
“When we made mistakes, our heads went down and they took full advantage.”
