Barcelona ace Cesc Fabregas has implored his teammates to improve their output against Celtic tomorrow night.
The Blaugrana host the Bhoys in their third Champions League group stage fixture and the former Arsenal captain has called for a better performance after edging Deportivo la Coruna 5-4 in La Liga on the weekend.
"It will be a difficult game against Celtic, it's always a tough game," said Fabregas.
"We won against Depor but it's clear we have to analyse their four goals.
"We simply have to improve on that because we conceded too often."
