The FA has launched an investigation after Newcastle United's coaching staff clashed with Liverpool's during their defeat by the Reds on Wednesday night.
The Magpies had gone ahead through Alexander Isak's debut strike, but Liverpool fought back in the second half Roberto Firmino equalised before Fabio Carvalho secured the three points for the hosts with a brilliant finish deep into added time.
Liverpool had become increasingly angry with Newcastle's time-wasting tactics and celebrated their last-gasp winner to the full. The celebrations of that dramatic goal sparked a furious reaction on the sidelines from the visitors, who moved towards the Liverpool staff.
