We can do better - Rodgers
Manager Brendan Rodgers admits Celtic can play much better despite making it two wins from two in the league at neighbours Partick Thistle.
Summer recruit Olivier Ntcham scored the only goal of the contest before the break, although the hosts believed they should have been awarded a late penalty following Nir Bitton's challenge on Miles Storey
"I'd need to see it again. It looked from where I was that Nir got a toe to it, and he was the right side of the defender," Rodgers told BBC Scotland. "We will play better, of course but tonight is a game we will look back on at the end of the season and hopefully say it was an important three points.
"We could have been more comfortable in the game if we had put our chances away, but when it is still 1-0 you have to defend," he added. "We didn't quite perform as well as I would want - our standards are much higher than we showed - but it shows the resilience and mentality in the team to get the result tonight."
