It came after groups of supporters joined forces over broken promises regarding the stadium move and transfer spending.
That march has since been called off by senior members of the group set up to arrange it but other fans are insisting they will still be protesting before the game.
And it comes after co-owner Gold was filmed defending himself to supporters when stuck in traffic on the way home from West Ham's dreadful 4-1 defeat at Swansea City last time out.
The incident follows similar episodes between fans and the owners in recent years and led to the fanbase facing criticism from pundits and rivals fans.
"You can understand the fans being angry (although) I'm not condoning for one moment them sort of surrounding David Gold," Cottee told talkSPORT.
"But David Gold is a very, very nice man and he DOES passionately care about West Ham United Football Club, there's no doubt about that."
Cottee also agreed that Gold's attendance at matches is evidence he cares about the club despite his advancing years.
However, the legendary West Ham goalscorer stopped short of offering up any defence of Gold's fellow co-owner Sullivan.
