Fulham manager Mark Hughes is closing in on PSV Eindhoven's Mexico international left-back Carlos Salcido.
But Hughes insists their pursuit of Salcido does not automatically mean Fulham's current left-back Paul Konchesky will be on the move.
"We have made enquiries," Hughes said after watching Fulham beat Port Vale 6-0 in the second round of the Carling Cup.
"He is a player I am interested in and we are hopeful it might be concluded."
Reports last night stated that Fulham had agreed a fee with PSV for the 30-year-old, who played at this summer's World Cup.
Konchesky has been linked with a move to Liverpool, where he would link up with former Fulham manager Roy Hodgson.
But Hughes said: "It is not a foregone conclusion that Paul Konchesky goes because we are looking to bring someone else in."
Blues improve N'Zogbia bid
Birmingham manager Alex McLeish is hoping for positive news from Wigan after making an improved bid for the Latics' winger Charles N'Zogbia.
The Scot is a long-time admirer of the 24-year-old French international, who seems destined for a move from the DW Stadium after his attitude was questioned by Latics boss Roberto Martinez.
McLeish would not be drawn on the size of the offer, although Blues have already had an £8m offer rejected, and says he is now waiting on a response from their Premier League rivals.
He explained: "We've put in another bid for Charles, we can only wait and see if it's successful. The board have worked hard to make these kind of things happen."
Potters warn off Chelsea
Stoke chairman Peter Coates is determined to keep Asmir Begovic out of the clutches of Chelsea.
Begovic is facing disciplinary action after missing the Carling Cup victory against Shrewsbury on Tuesday.
Manager Tony Pulis claimed the Bosnian goalkeeper had refused to play but Begovic says it was due to a misunderstanding.
"This is an internal matter -- and we will decide on what action to take," Coates told Sky Sports News HD. "Asmir Begovic remains our player.
"We are not interested in any new offers from Chelsea."
