Harry Redknapp feels it would take 'big money' to bring Marseille full-back Taye Taiwo to Portsmouth.
Following injuries to Dejan Stefanovic and Noe Pamarot, Redknapp is keen to bring in a left-sided defender during the transfer window.
He has been linked with Marseille's Nigeria international Taiwo, who has previously attracted interest from Valencia.
Redknapp is aware of the player, but suggested he would have to pay over the odds, if he wanted to sign Taiwo.
"We haven't got a lot of cover at the back," admitted Redknapp.
"I know about Taye Taiwo, but I think he'd be big money and he's just a name.
"I've got loads of names and whether we can do anything I don't know.
"If I can't get the right players then we won't bother and we'll keep going with what we've got."
