Sam Allardyce insists he never intended to "upset" Jurgen Klopp after the Liverpool boss took offence over comments made about his methods.
And he hopes the pair haven't fallen out despite their second spat in the space of a week.
In a radio interview the Black Cats boss, who last week called Klopp a "soft German", offered his thoughts on Liverpool's current injury crisis which has sidelined 10 first-team players, six of whom have or are recovering from hamstring injuries.
"That is him asking his players to play a high-tempo pressing game from the top end," Allardyce told talkSPORT.
"I don't think Jurgen has realised just how ferocious our league is at this period of time and because he has asked for that extra-high energy - that extra 10 yards - these lads are fatiguing now with so many games in such a short period of time and are picking up these muscle strains."
It led to the Reds boss dismissing Allardyce's criticism of his methods by insisting he is not overloading his players with running.
"I am glad for Sam, such an experienced manager, that he has time to think about Liverpool's problems - I don't have time to think about this," said Klopp.
"I knew about the Premier League, the fixtures, the intensity of the football here."
Allardyce moved to calm the waters though at his press conference, adding: "I think the headline has upset him in the nationals.
"I got asked a question by a friend of mine, Alan Brazil, on talkSPORT, 'What do you think the injuries are down to?', and I gave an opinion off the question that Alan asked me, which was perhaps the high-pressing game in all the games that they have had created that little bit more fatigue and that was maybe a cause of why they have picked up so many hamstrings.
"It was a question that Alan asked me, I answered it and never expected it to bring the headlines it's brought.
"But if Jurgen is listening, I didn't mean to upset you or criticise your club in any way, I was just giving what I could see as as maybe one of the reasons why we get injuries.
"I am very wary of the amount of work we do in the week now in the hope that our players have enough energy to do the running they need to do in this period of time to try to get a result, and we are all suffering because of it.
"I'll probably suffer some injuries, no doubt, by the end of next week when we have played three games in a short period of time, but we are trying to manage it.
"I was just trying to say that he hasn't experience this level of football before and maybe that might be one of the causes."
Asked if the pair had fallen out, Allardyce replied: "I hope not.
"I had no intention of trying to wind him up. Alan asked me to talk about Sunderland, he threw the question in at the end and maybe I should have said, 'It's not for me to answer, it's for Jurgen'. I don't know."
