Ange Postecoglou has admitted Celtic weren't at their best despite coming out 2-1 winners against Motherwell.
Kyogo Furuhashi's early tap-in had the visitors in the driving seat before fellow countrymen Daizen Maeda came off the bench to double the advantage with six minutes to play. However Ross Tierney responded with a magnificent volley to set up a nervy finish as the Steelmen showed a fighting spirit until the end.
And despite Celtic having the bulk of the possession during the clash the Parkhead boss believes his men made things to complicated for themselves and ultimately had to grind out three points at Fir Park, which keeps them seven points clear of Rangers at the top of the Scottish Premiership. "It was a grind today. We had to work awfully hard," admitted Postecoglou on BBC Scotland. "Credit to Motherwell, I thought they worked awfully hard themselves to disrupt our play and we just never got into any sort of rhythm today.
