Last year it was revealed that Whymark was living with Alzheimer’s, having been diagnosed in late 2019.
His family noticed “subtle changes” in his memory and mood, which they originally put down as a form of grief after his mother died.
Speaking previously, Whymark’s son, Craig, said: “It’s really touching that people still remember dad and with such fondness.”
Since his death football fans have flooded social media with tributes to the former star, with one describing him as a “brilliant, underrated striker and lovely, unassuming man”.
One described him as an “unsung” hero of the Robson era.
A Grimsby Town fan said it was a “privilege” to see him wear the “black and white stripes”.
