Rangers looked set to claim a valuable Old Firm derby win at Broadwood until Caitlin Hayes’ 99-minute equaliser secured a share of the spoils and keep Celtic ahead of their fierce rivals in the league.
In footage captured by Sky Sports following the match, Rangers assistant manager Craig McPherson appears to aim a headbutt at the back of Alonso's head as the two sides were shaking hands.
Speaking to Sky as the footage was shown to him, Alonso said: "I don't know. You can see there, somebody pushed me from behind. I never talked to (McPherson) the whole game.
🗣️ " We can't have that in football at all"

"It's obviously disappointing to concede a goal in the last minute, I totally get it. But I don't know. I was called a 'little rat', I don't know why."
When asked about the incident, Rangers head coach Malky Thomson told the broadcaster: "Without me seeing it at all I don't know that I can comment on it.
"If that's the case, then there will be an investigation and we'll obviously look at it."
