In November the Arsenal midfielder revealed that he had helped to create a biotech company that he believed could be a major player in an energy market worth a potential £20billion.
A factory in Caserta, Italy, produces nearly 10,000 tonnes of levulinic acid a year, a product that it is believed can replace oil in numerous products in sectors such as pharmaceuticals and cosmetics. Nearly 500 people have jobs thanks to GF Chemicals, the company Flamini founded in 2008.
Now the midfielder has revealed that his manager will be a major inspiration to him even after he retires.
"Arsene is a kind of mentor for me," he told the Financial Times. "He is someone who will always keep his calm, and I have learnt from him never to take a decision in the heat of the moment.
"When you [come on to] a football pitch, there is passion, there is adrenalin. I'm quite calm off the pitch. But on the pitch, I transform myself. I become sometimes aggressive – in a good way."
He added: "Business is something I developed on the side of football and will probably be in my life after football. But today I am a football player and I dream about football and I eat football every day."
