Kyogo Furuhashi struck the match-winner late in the first half Sunday as Celtic defeated Rangers 1-0 away in the Scottish Premiership's first Old Firm derby of the season.
The Japan international rocketed a half-volley from outside the area after Matt O'Riley lofted a long header over the Rangers defensive line in the second minute of stoppage time at Ibrox Park.
The home fans had earlier voiced their displeasure after seeing one Rangers goal canceled for offside and another disallowed for a foul following an on-field video review.
Furuhashi had been unable to capitalize on a pair of scoring opportunities before bagging his third goal of the season and sixth from five Glasgow derby starts since moving to Scotland in the summer of 2021.
The win moved the defending champions to the top of the table ahead of Motherwell on goal difference, while giving them a four-point buffer over Rangers after four games.
Elsewhere in Europe, Japan forward Ayase Ueda opened his account for Dutch champions Feyenoord, netting in the 71st minute of their 5-1 demolition of Utrecht in the Eredivisie.
The 25-year-old transferee from Belgian side Cercle Brugge came off the bench 10 minutes after the break and gave his team a 4-1 lead with a composed turn and finish past Utrecht keeper Vasilis Barkas.
