Millwall chairman Theo Paphitis has hit out at Blackburn Rovers over their £2m offer for midfielder Steven Reid.
Reid has come through the Millwall ranks
The Lions turned down Rovers' bid and the Premiership club refused to budge in their bid for the Republic of Ireland international.
But Millwall are equally determined to hold out for more money for their highly-rated midfielder who is also attracting interest from Portsmouth.
"The way they offered us payments was unacceptable," said Paphitis.
"To be honest, I think they thought they were shopping out of the Littlewoods catalogue.
"We'll sell someone if the right offer comes in and we think we can strengthen our squad with the money.
"Steven will be an important part of our promotion campaign so if he's not going to be there, we need to replace him.
"If we can't fill several positions, we won't sell the player and it's as simple as that.
"But I'm confident that, if it's not Blackburn, someone else will come in for him. I've no doubts about that whatsoever and neither does Steven."
Portsmouth are also unlikely to improve on Blackburn's £2m offer.
Fratton Park chief Harry Redknapp said: "I like Steven Reid, he's a player with a big future and I'd love to get him.
"He'd cost £2m but I don't know if we could afford that sort of money."
Reid began his playing career at Millwall in 1997 and has made 139 first-team appearances for the club.
Millwall manager Mark McGhee also suggested that the midfielder would continue his career at the New Den unless the club got an offer they could not refuse.
"We don't have to sell players and if anyone wants any of them, they'll have to pay top book," said McGhee.
"We wouldn't stand in a player's way if we're offered serious money and he has the opportunity to play in the Premiership.
"Steven knows about the offer for him and is relaxed about us not accepting it."
