Police officers had to intervene after a touchline row between Jürgen Klopp and Sam Allardyce during which, he says, the Liverpool manager used ‘foul and abusive language’. Speaking after the match at the Stadium of Light on Wednesday night, the Sunderland boss calls Klopp a ‘soft German if he thinks that’s a red card’, referring to Jeremain Lens’ late tackle on Mamadou Sakho.
