Twenty-four hours earlier at Selhurst Park, before taking a throw-in that set up Crystal Palace’s winner against Liverpool, Jefferson Lerma was allowed to use a towel in stoppage time. That is why any team coached by Sam Allardyce or Tony Pulis would have the ball boy or girl waiting with a towel in hand. That the only towel visible on Sunday was the keeper’s suggests that Newcastle had not agreed or Arsenal forgot to ask. It just makes Newcastle look bad and is another example of the Magpies not being the club they were in the 1990s when they were everyone’s second team. If you can get an advantage you are going to take it, but it is not a great look.
