Celtic defender Kelvin Wilson has lamented his side's lack of concentration in the final minutes of their Champions League clash against Barcelona at Camp Nou.
The Scottish champions were drawing 1-1 with the Blaugrana until the fourth minute of injury time, when Jordi Alba scored the winner for the hosts.
"It's never over until final whistle," he said. "You need to concentrate more against these types of players.
"I did okay - the whole team defended very well. Our manager Neil Lennon is gutted more than anything.
"We matched them for long periods. Goalkeeper Fraser Forster is up there with England number one Joe Hart."
The 2-1 loss in Spain leaves Celtic in second place in Group G with four points from three matches.
