World Cup winner David Trezeguet has been unveiled as the latest Indian Super League signing, joining FC Pune City.
Stuart Gray is still waiting on the 'green light' to bring in new players as his hands are tied by a takeover delay.
West Ham boss Sam Allardyce claims he knows nothing about any possible move for former Newcastle striker Obafemi Martins in January.
The Hammers are in the market for striking reinforcements when the transfer window reopens next month after struggling for goals so far this season.
Martins, who currently plies his trade in America with Major League Soccer side Seattle Sounders, has been mentioned as a possible target to bolster their attacking options.
However Allardyce, who worked with Martins during his time in charge of Newcastle, says he is in the dark over reports linking the Nigerian with a loan move to Upton Park during the MLS off-season
"I haven't heard anything about Oba," said Allardyce. "He's playing in America at the moment.
"Everyone knows if we're in the market for a player, we'll be linked with everybody. We'll deal with that - speculation is speculation."
