Nasri has pin-pointed exactly what led to his eventual decline in football, despite a flourishing career.
In 2018, Nasri was found guilty of receiving an intravenous drip and was effectively banned for 12 months.
The Frenchman has admitted that it was hard to make a comeback from the sensational doping scandal that rocked him a few years ago.
Nasri, now 34, was found guilty in 2016 after visiting the Drip Doctors medical centre.
At the time, Nasri was on loan at Sevilla and after serving 12-month ban, he was allowed to return back to the game.
“What happened in Los Angeles ruined my season,” he told The Sun.
It was an injection of vitamins that was legal and I had prescription.
“I was destroyed because I thought I was going to be banned for two years.
“I didn’t to play anymore after that. I even told [Sevilla boss, Jorge] Sampaoli to leave me out, but he always wanted me to play.
He was initially banned for six months but his punishment was backdated, effectively ruling him out of action for most of 2018.
The former Manchester City winger was found guilty of receiving intravenous drip of 500 milliliters of water containing nutrients.
Nasri has since had underwhelming spells with Antalyspor and West Ham United, while also having a brief stint with Anderlecht in 2019, which was being coached by his former teammate Vincent Kompany.
