Manager Harry Redknapp has angrily denied reports that he is set to walk out on Southampton because of the arrival of Sir Clive Woodward.
The former England and Lions rugby union coach begins his new job as the Saints' technical director on Monday.
But Redknapp insisted on the club website: "It's nonsense to say I'm going to walk out.
"I'm fed up about reading all this stuff about Clive Woodward and that I'm going to answer to him. It's rubbish."
Woodward's arrival at St Mary's - and the exact role he will take on - have long been the subject of speculation.
Saints insist that the appointment could only be officially confirmed after the Lions tour to New Zealand was concluded.
The club's website states that he will be involved in "three key areas" and will "help on the medical side and with team support and structures, as well as individual coaching".
But one press report claimed he would be in a higher position than Redknapp - sparking an angry riposte from the Saints manager.
Redknapp continued: "I don't know where the story has come from but it's rubbish and it does me no favours at all.
"I've spoken to Clive again and he said he wants to come in and sit and watch and learn. Then, suddenly, there's a headline saying 'Harry must obey Sir Clive'.
"I'm fully focused on getting some new players in and preparing the team for the start of the season.
"That's all I'm thinking about. If I wanted to walk out, I would have gone in the summer.
"I am the manager and will have complete control over the first team - that won't change.
"He will work with the academy and have an input with sports science and on the medical side - that is fine by me.
"Sam Allardyce has used a lot of these ideas and technology to good effect at Bolton, so there may be things we can learn."
Chairman Rupert Lowe added: "It has all been agreed and approved with Harry, who has been kept in touch throughout.
"Clive's job will be to take care of the responsibility for organisation which leaves Harry free to concentrate on football matters."
