Celtic manager Neil Lennon has hit out at his team's defending following their 3-2 defeat at Ross County.
The Hoops boss said that his side should have killed off their opponents by half time, but gave away sloppy goals.
"We should've been four up at half time and we've lost two really bad goals. The third goal's shocking," he told BBC Sport.
"I want players here who are prepared to role their sleeves up. I'm expecting better from Celtic players. Defensively, we looked very, very fragile."
Goals from Charlie Mulgrew and Gary Hooper put Celtic into a 2-0 lead, but County hit back through Grant Munro and Sam Morrow before Steffen Wohlfarth netted a stoppage-time winner.
