Chelsea have expressed their disappointment with the section of supporters who disrupted the minute's silence on the 23rd anniversary of the Hillsborough disaster.
The tragedy saw 96 people die during the FA Cup semi-final between Nottingham Forest and Liverpool on April 15, 1989, with many details still to be made public.
FA Cup semi-final weekend regularly marks the disaster with a minute's silence at grounds across England, but prior to the game between Tottenham Hotspur and Chelsea, fans of the Blues tarnished the silence at Wembley.
"Chelsea Football Club is extremely disappointed that a very small minority of fans embarrassed the club today by not honouring the moment's silence before kick-off," a statement read.
"Chelsea FC believes all moments of respect should be honoured and today we pay our full respects to all those that suffered as a result of the Hillsborough disaster 23 years ago.
"The club will be working with Wembley and the FA to identify those responsible and if we are provided with evidence that season-ticket holders or members have been involved we will take the strongest possible action against them."
Many families of the 96 who died during the Hillsborough tragedy are still searching for answers surrounding the afternoon's events in Sheffield over two decades ago.
In October last year, Parliament agreed to release documents relating to the tragedy could be made public.
Liverpool marked the weekend's remembrance by beating Everton 2-1 at Wembley, with Luis Suarez and Andy Carroll both on the score sheet.
