West Ham have passed on their best wishes to the club's co-chairman David Gold as he recovers from illness.
Gold, 76, is in hospital recovering from pneumonia after being taken ill following the FA Cup third-round clash with Manchester United.
Allardyce said he had yet to speak to Gold (above left), who also needed hospital treatment for cholangitis and septicaemia in March 2011, but wished him well and moved to assure supporters the club's January transfer window recruitment drive will not falter in his absence.
"Myself and all the players will be wishing him well today. I only found out yesterday that he was poorly," Allardyce said. "We will get a message to him in the very near future and wish him a speedy recovery.
"I think that there's always a communication line to him if David needs to (be contacted). In terms of what we're doing at the moment, we're as active as everybody else.
"If there's a player there that we think can improve the squad we'll try to move on him."
One player who is certainly a target for the Hammers is Blackburn left-back Martin Olsson.
Reports earlier in the week had suggested Rovers wanted at least £7million for the 24-year-old Sweden international but Allardyce reckons that is wide of the mark.
"I don't think that's true, no, but we have made an enquiry," he said.
Allardyce said there were "ongoing negotiations" and added: "I think that if I was strengthening anywhere at the moment it would be in the left-back position because of our injury problems in that area at the moment. We are only looking at that position at the minute."
