Celtic boss Brendan Rodgers says his side has plenty of work to do despite drawing 3-3 with Manchester City on Wednesday.
The Hoops thrice led Pep Guardiola's side in the Champions League fixture at Celtic Park in what was a vastly different display compared to their 7-0 defeat at Barcelona a fortnight ago.
Having beaten Kilmarnock 6-1 on the weekend to take a four-point lead on the Scottish Premiership with a game in hand, things are in good order at Parkhead, but Rodgers is looking for improvements.
"I can't ask for any more from the players that we have at the moment," he said.
"There is a real great feel around the club at the moment.
"I hope tonight is a real good marker and measure of how the players have improved but I know there is a long way to go in terms of where I want to be."
