Koji Yamase scored a contender for goal of the season as visiting Yokohama F Marinos put another dent in Gamba Osaka's bid for back-to-back J. League titles after a 1-1 draw on Saturday.

Yamase's 44th-minute strike looked to have condemned Gamba to their third defeat on the trot until Magno Alves struck his 17th goal of the season with four minutes remaining at Expo Stadium.

Magno Alves could have had a hat trick and it was very much a case of two points lost for Akira Nishino's men, who trudged off the pitch knowing the result has presented the Urawa Reds with a great chance to put daylight between themselves and the defending champions.
