Marsh built his business by sending out countless speculative emails to potential private clients after returning from his season in the yachting world. One of the first respondents was from De Bruyne, who asked Marsh if he had cooked for other celebrities before. That led the young chef to 'fudge' the truth, telling De Bruyne he had a bevvy of clients before outlining his specific methods. De Bruyne asked him to start the following Monday, before recommending him to Ilkay Gundogan, with whom Marsh built a close relationship.
"I never eat with players. I’ve never eaten with a player except Ilkay," Marsh said. "When you do six years with someone, I knew everything about him, he knew everything about me."
"That man loves football, all he did was play Football Manager. He was obsessed with it. I am so happy he’s at Galatasaray. We used to talk about him playing for Galatasaray almost daily. That’s his team, he’s supported them his whole life. I’m so happy he’s gone there."
John Terry forced Marsh to up his game. The ex-Chelsea and England captain reached out to Marsh after he had appeared in a BBC Sport video about the individuals who worked behind the scenes in football.
"John was the guy that made it clinical. How things were prepped, how things were cooked, how things were packaged, how things were stored, how things were delivered. He liked things weighed out and labelled.
"He’d FaceTime me every night to ask how heating instructions were done. He always said to me, 'We’re part of the one per cent club, Jonny. It’s all about the one per cent'."
After Terry shared Marsh's page on Instagram, requests came pouring in. The chef now has more than 850,000 followers, with his Day in the Life videos offering a peak into the eating habits of his famous clients.
