The tourists are staring at another heavy defeat and a 5-0 series whitewash in the final Sydney Test after a first innings capitulation and trailing Australia by 311 runs with six wickets intact at the end of day two.
England's plight was underscored by Cook's inexplicable decision not to play a shot and a trapped leg before wicket by Ryan Harris on the second ball of the day as a prelude to the tourists' collapse to be all out for 155.
"He (Cook) is not contributing the weight of runs that we have come to expect from him. He's not been at his best and he's been under pressure from the Australian bowlers but he's still delivered a little bit," Gooch told reporters.
"Ultimately, the individual is the only one who can make that decision, but for me he's still a guy who is learning and who should be there when some kind of rebuilding takes place."
"He made an error in judgement which happens to any batsmen. It's particularly poignant when it happens like that at the beginning of the day when you're trying to set the tone and you're trying to lead from the front," he said.
