And Chelsea manager Emma Hayes said after the match: “We have seen in the growth of the game that there is this sense the players are more in demand.
“So I think it should serve as a reminder to us all and the stadiums and stewards that we have to put player protection first.”
Reports suggested the Metropolitan Police could not investigate the incident as the fixture was not a designated match under the Football (Offences) Order.
However, the Home Office said Women’s Champions League games do come under designated matches and so should be open to investigation.
A Home Office spokesperson told BBC Sport: “Football banning order legislation covers both women’s and men’s designated matches where there is a high risk of disorder, and matches in the Uefa Women’s Champions League and women’s international matches fall under its scope.
“Matches are designated based on the history of incidents and the assessment of risk. Where matches are not designated, they are subject to generic public order legislation that applies to them as well as other sporting events.”
