Premier League clubs have ramped up security measures around their pitches following a spate of protestors attempting to attach themselves to goalposts.
Amid mounting concerns about the prospect of more games being hit by lengthy delays, clubs are reviewing and drawing up detailed plans preparing for numerous potential scenarios they may need to react to in a bid to thwart demonstrators' bids to disrupt matches.
Tottenham's 3-1 win over West Ham on Sunday was the latest game impacted with six arrests made following incidents in the second half.
Two protestors tried to take advantage of the fact most eyes were elsewhere following a flare-up between both sets of players and storm the pitch to reach one of the goals.
