New Barcelona signing Sergio Aguero has reportedly undergoing treatment on his knees in a bid to try and help prolong his football career.
The 33-year-old has had stem cell treatment which is aimed at regenerating the cartilage to allow the Argentine to play longer, according to Cadena SER.
The report adds that the procedure was carried out by Dr. Robert Soler at the Institute for Tissue Regenerative Therapy and was planned before the striker’s move to Barcelona.
Sports stars such as Pau Gasol, Rafa Nadal, Carles Puyol, Martin Odegaard and Érik Lamela are mentioned as athletes who have also undergone this kind of treatment.
