The Ivory Coast international has been linked with a potential mover to one of London’s biggest clubs in the last few weeks ahead of next month’s transfer window.
Zaha has scored four times in 13 appearances in the Premier League this season to help the Eagles hoist themselves up to 16th place in the table.
The African forward has regularly been linked with a move to Tottenham over the past two or three seasons but a move failed to materialise.
Zaha, though, has started to attract interest from defending Premier League champions Chelsea as well as current leaders Manchester City.
Asked about whether the Palace winger could leave in the January transfer window, manager Hodgson appeared to open the door for Zaha to leave.
“If Wilf continues as he is doing, then the club will be faced with a situation where someone wants to put a lot of money on the table in order to prise him away,” Hodgson told his pre-match media conference.
“That will be a massive decision for the club because I know how much everyone at Crystal Palace appreciates him and he is the last person we want to lose.
“It is no good making bold statements that this and that won’t happen because things do happen and when they do, you deal with them.”
Zaha has scored 20 times in 128 games in all competitions at Palace since his return to Selhurst Park from Manchester United.
The Ivory Coast international spent two seasons at Manchester United but the Ivorian made just four appearances for the Red Devils team.
The African starlet has netted two goals in eight appearances for his national team.
