Salako, who coaches at Palace, says Chelsea's game would suit the Ivory Coast star the best.
"Of course (there is a concern that he may leave in January). I think Chelsea would probably be the best home for him after their ban," he told Lovesport Radio.
"They really have an exciting young team there and Wilf can come in and add to that.
"He may well move there, but Arsenal can also come back with the money. Anything can happen."
