Lyon have secured the services of promising defender Emanuel Mammana from River Plate for €7.5 million.
The 20-year-old has signed a five-year deal with the Ligue 1 outfit.
Mammana had also been linked with Chelsea in recent months, but has made the decision to continue his career with Lyon instead.
I am very proud to have signed for a big club like Lyon, the defender told OLTV.
I will do everything within my powers to reward the club for the faith shown in me. I have arrived at a big club to learn and to win titles.
Mammana came through the ranks of the River Plate youth academy and made his official first-team debut in October 2014. The centre-back had already made his Argentina debut by then, featuring in the friendly win over Slovenia in June of the same year.
He becomes Lyon s third new arrival ahead of the 2016-17 campaign following the previous capture of Maciej Rybus and Nicolas N Koulou.
