Chelsea and the Metropolitan Police are investigating after a fan confronted Newcastle goalkeeper Martin Dubravka during Tuesday’s Carabao Cup quarter-final at Stamford Bridge.
A Chelsea supporter entered the field of play and appeared to push Dubravka after Mykhailo Mudryk scored a stoppage-time equaliser to take the game to penalties.
After Chelsea won the shootout 5-4 to seal a semi-final spot, Mauricio Pochettino and Eddie Howe both condemned the fan.
Pochettino said: "We need to be careful. The fans need to be careful with this type of thing because it's a thing that can put in danger the players.
"I'm disappointed. I don't agree with this type of thing that happened here in Stamford Bridge and in other stadiums in England or around the world. It's always disappointing with this type of thing because it's dangerous."
Asked if greater protection was required, Howe said: “Definitely on the evidence of that. I always say the safety of players, coaches manager, referees, linesmen [is] the priority at any football match. More has to be done to keep irate supporters away from everybody.”
