Joey Barton has issued an apology for a tirade of abuse he aimed at former Liverpool midfielder Dietmar Hamann, admitting his comments were "offensive" and "untrue".
The row flared on Monday on Twitter with Barton responding to the news his Marseille team-mate Loic Remy had chosen to join QPR ahead of Newcastle, suggesting managing director Derek Llambias might be one of the reasons behind the decision.
Hamann replied, advising Barton to stay out of the business of his former clubs, leading to Barton making a series of allegations and labelling the former Germany international a "maggot" and a "dog". He took back the remarks on Wednesday evening.
"On Monday evening tweets exchanged between Dietmar Hamann and I went beyond the boundaries of banter, opinion and common sense," Barton said via Twiiter.
"I accept that my comments were offensive, untrue and related to matters of a personal nature, of which I had no knowledge. I have apologised to Dietmar personally and now wish to apologise through the same social media channels that I used to make them, as well as my own website.
"I appreciate my comments have caused Dietmar and his family some distress and I fully regret that.
"I also appreciate that my comments should not have been made, as they could have damaged Dietmar's reputation, which should remain intact as a fantastic player and ambassador for German Football, as well as the game in general.
"Dietmar and I have now agreed to draw a line under the unfortunate exchange and neither of us will be making any further comments on the subject."
