Celtic restored their seven-point lead at the top of the Scottish Premiership with a comfortable victory over Hearts at Tynecastle.
Matt O’Riley led the way with a superb early opener then Daizen Maeda added a close-range finish.
Reo Hatate hit the post with a second-half penalty before Kyogo Furuhashi continued his knack of scoring against Hearts.
Lawrence Shankland found his first goal since August but Celtic regained their three-goal advantage in a one-sided contest thanks to a fierce Tomoki Iwata strike.
For the champions it was a 10th successive win over Hearts in all competitions, with the Edinburgh side staying in fourth place, despite winning just three of their nine outings.
Celtic boss Brendan Rodgers had talked of enjoying the hostile atmosphere at Tynecastle but the home support were silenced by a wonderful goal after just four minutes.
Coming in from the left, Luis Palma dinked the ball over the top of the Hearts defence and O’Riley let it drop over his shoulder before steering a sweetly-struck volley into the far corner of the net.
Kenneth Vargas and Maeda traded shots before the latter doubled Celtic’s lead. Hatate drilled the ball across the face of goal and his Japan team-mate had the simple job of nudging it home.
The second half was just 12 seconds old when Alex Cochrane was penalised for a clumsy challenge on Kyogo. However, Hatate cracked the spot-kick against the base of the post.
The miss did nothing to affect Hatate’s confidence as he sent a sumptuous flick into the path of the galloping Palma and seconds later Kyogo was lashing the ball high into the net from six yards to stretch his scoring run against Hearts to eight games.
There were already a lot of empty seats in the home stands when Shankland curled in a lovely finish from the edge of the penalty area, profiting from a bad Maeda touch.
The hosts had 25 minutes to salvage something and the introduction of Liam Boyce added a bit of bite to their attack, but Celtic were next to strike as Iwata crashed in his first goal for the club.
The visitors were first to the ball each time in a series of near things before the substitute thundered a shot off the underside of the crossbar.
Celtic remain unbeaten in the league, winning each of their opening five away matches, something no team has done since 2017-18 during Rodgers’ first spell in charge.
