Phil Neville says Manchester United defender Jonny Evans should be “embarrassed” over his spitting incident at Newcastle United.
Neville says Evans and Newcastle United striker Papiss Cisse should face bans after appearing to spit at each other.
Referee Anthony Taylor spoke to Evans and Cisse after the first-half incident on Wednesday, but neither were booked.
Former Manchester United defender Neville said: “It’s unacceptable. Both those players will be embarrassed.”
Ex-Newcastle player Didi Hamann also said: “This is not acceptable. It’s disgusting.
“There are kids watching. Something has to be done. The behaviour towards each other and the referee is deteriorating on a weekly basis.”
