"It's a great joy for me to officially sign with the Toulouse Football Club," Mvoue who captained Cameroon to the 2019 U-17 AFCON title told the club's website.
"For a long time, and even since my first visit here, I had this desire to engage with the club, and work with people I know and with whom I get along very well.
"Now I want to focus only on the field, and perform with the club. I will first have to recover from my injury. I'll be patient, and I'll come back even stronger!"
The teenager also thanked Eto'o, whom he referred to as his father on social media via his official Twitter account as he revelled in the next stage of his promising career.
