Harry Redknapp described Gary Neville's view on Tottenham as 'absolute rubbish' as the pair's ongoing feud about the club shows no signs of subsiding.
Redknapp took issue with Neville's suggestion on Monday Night Football that Tottenham have been 'spineless and soft' but the pair have since ramped up the bad blood.
Early on Friday, Neville took to Twitter to post records and win percentages from his time at Valencia, Redknapp at QPR and again at Birmingham having seen his time in La Liga used by the former Tottenham manager earlier in the week.
Redknapp rarely bites his tongue and had no desire to let Neville have the final say and so the 71-year-old continued to voice his annoyance at the former Manchester United defender on the radio.
'To say that for 30 years Tottenham have been spineless, gutless, useless, disgraceful – that's absolute rubbish,' Redknapp repeated on Friday's Alan Brazil Sports Breakfast.
'So now he's got to dig up that his win percentage was one per cent better than mine at QPR… I took over a QPR team that had already played 14 games in the Premier league and they had two wins, so it wasn't exactly taking over a world class team, you know?
'And at Birmingham I took over a team that had gone 25 games and only won one, that wasn't easy.
'My argument was about the Tottenham team I had, and I will not stand by and let someone come out with a statement like that when their facts are completely wrong.'
The feud came to life after Redknapp took issue with comments made by Neville about Tottenham after the defeat against Manchester City at Wembley.
In a heated debate with fellow pundit Jamie Carragher, Neville said: 'Tottenham for 30 years of our lives were spineless and soft, flaky, rubbish, you could be 2-0 down against them and think you would win 5-2.
'That's just the way they were. You knew that one little bump during the game and they would fall over it.'
Redknapp managed the club between 2008 and 2012 - he had a win percentage of 49 per cent, a figure omitted by Neville for the sake of his Twitter post - and having already hit back once on the radio, he wanted a second go after Neville's Twitter antics.
He added: 'He could say: "Yeah, but you didn't win anything. You got two fourth place finishes and the quarter-finals of the Champions League, but you didn't win anything".
'Well the present team have had four years [under Pochettino] and they haven't won anything either, but does it make them a bad team? No it doesn't! I love watching them and I love the manager.
'We all know Gary, he is an excellent pundit and was a great right-back, but he's opinionated and sometimes he goes over the top. He hasn't got his facts correct in this case and he should have thought a little bit more about what he was saying.
'Yet, he's not man enough to say: "Yeah I was wrong, I'll hold my hand up, that team Harry had was a good team".'
