Toon manager is keen to tie striker to a new deal, but says he could be sold next month.
Newcastle boss Alan Pardew has admitted that Arsenal target Demba Ba could be sold in January.
Ba has a reported release-clause of just £7.5m and has frequently linked with a move to the Gunners.
The prolific striker has been on fine form for the Magpies this term, scoring 11 goals in just 18 Premier League appearances.
Pardew says he is keen to tie Ba to a new contract, which does not include a release clause, if he stays at St James’ Park but admits he could depart next month.
“We will either move Demba on or we will secure him in the summer,” said the Toon boss told the BBC.
“Really and truly this window is the key, I think, because if Demba goes in this window, it will cause us a problem,” he added.
“I think he will stay, but there’s a possibility he could go because of the clause that’s still in force.
“In the summer – I won’t let it run until the summer. I’ll do something about it.”
QPR have also been linked with a move for the Senegal international but the former Hoffenheim striker has describe a move to Arsenal as a ‘dream’.
Ba has scored 27 goals in 53 Premier League appearances since joining Newcastle on a three-year deal from West Ham United in June 2011.
