Japanese forward Kyogo Furuhashi scored his league-best 19th goal of the season for Celtic in the Scottish Premiership on Sunday as the leaders cruised past St. Johnstone 4-1 away from home.
Furuhashi's low cross led to a 13-minute own goal before he made it 2-0 nine minutes later, controlling Jota's ball into the box and blasting home to net for the second straight game.
Drey Wright got one back with a long-range effort, but Aaron Mooy extended Celtic's lead before the break and David Turnbull added another near the full-time whistle, with the home side reduced to 10 men late on.
Furuhashi came off in the second half, as did compatriots Reo Hatate and Daizen Maeda.
Japan attacker Takefusa Kubo was named man of the match in a losing effort for Real Sociedad, whose 1-0 defeat to visiting Valladolid snapped a seven-game unbeaten streak in Spain's La Liga following their most recent loss in October.
