He's had his say.
Netflix really stepped up to the plate this Christmas time.
There was some excellent stuff uploaded over the festive period, and it gave us some pretty excellent excuses not to leave the couch too.
Those were the days...
And one of the best pieces of content that was uploaded was the Sunderland Football Club documentary, entitled Sunderland 'Til I Die.
One of the stars of the show was Simon Grayson, who was in charge of Sunderland at the start of the 17/18 season.
He was sacked from the job halfway through the season as the side were facing potential relegation, and was replaced by Chris Coleman.
Grayson was a guest on BT Sport on Saturday, and he discussed the subject of the documentary in detail.
Grayson said that he knew that there was an issue in the club from the start, saying that: "Alarm bells started ringing after two days."
He also criticised Netflix for how they went about their business, but also said that he might be somewhat to blame: "We created a real good atmosphere at the training ground and it was brushed over. I didn't give them the access they probably wanted."
He did admit that it made for good television though...
