Wigan owner Dave Whelan has warned Roberto Martinez that he will have very little input with regards to Liverpool's transfers dealings if he lands the vacant manager post at Anfield.
Latics boss Martinez is part of Liverpool's six-man shortlist to replace Kenny Dalglish and Whelan has urged the Spaniard to think carefully about relinquishing traditonal managerial powers.
Whelan told ESPN: "My information is that the new Liverpool manager will not be given full responsibility of the football department.
"There will be somebody else signing players, and they might not necessarily be the choice of the manager.
"My advice to Roberto is to think very carefully about this, but Liverpool are a big club and I hope that they remain one of the big clubs.
"But I have to say from what I am hearing the new Liverpool set up on the football side goes well beyond the norm even with a director of football."
Whelan also criticised the Liverpool process of seeking a 'beauty parade' of six managers to head to Boston for interviews with owners Fenway Sports Group, and insisted reports that Martinez is going to America this week are wide of the mark.
Whelan told ESPN: "My understanding is that Liverpool are seeking a final shortlist of six managers whom the owners would like to interview.
"I am amazed that they think they can do that, it sounds very much an American way of dealing with these issues in sport, but I would wonder how those six managers might feel.
"I spoke with mine only yesterday and he is on a week's holiday in my home in Barbados. The weather is wonderful. Nothing will happen until he returns, which won't be until next Tuesday, so reports that he is flying off to Boston today to have talks are not right.
"In fact, he was relaxing on a sun lounger the last time I spoke to him yesterday, he had a mentally exhausting season and he needs the rest.
"He has not said anything to me yet about what he plans to do, but I have told him what I think about it, of course I have. I have told him it doesn't feel right what is happening at Liverpool, but its for him to make his own mind up."
