Japan forward Kyogo Furuhashi extended his hot streak with a sixth goal in six games as Scottish Premiership leaders Celtic beat Kilmarnock 2-0 on Saturday.
Ange Postecoglou's side moved 12 points clear of second placed Rangers thanks to Jota's opener and Furuhashi's decisive finish.

Japan international Maeda cut the ball back and Jota was perfectly placed to finish from just a few yards out.
Furuhashi put the result beyond doubt in the 51st minute following a lethal Celtic counter-attack.
Reo Hatate sent in a low cross which was diverted towards goal by Furuhashi, with the shot taking a deflection before flashing into the net.
