Celtic head coach Fran Alonso appeared to be headbutted from behind by a member of the Rangers coaching staff following a dramatic 1-1 draw in the Scottish Women's Premier League.
The visitors were celebrating a 99th-minute equaliser when Rangers coach Craig McPherson approached Alonso after the full-time whistle at Broadwood.
Talking to Sky Sports, Spaniard Alonso said: "Someone pushed me from behind. I never talked to him the whole game. I was called a little rat, but I don't know why."
