Cristiano Ronaldo to undergo stem-cell therapy in order to boost his fitness for Man City clash

Real Madrid’s star man Cristiano Ronaldo will undergo stem- cell therapy in order to rush up his fitness and make him fit for the second leg champions league tie against Man City according to reports. Stem cell therapy or treatment is a medical treatment process whereby doctors collect a sample of healthy cells from the player’s blood or bone marrow, which is then injected into the problem area to help speed up recovery.
Ronaldo didn’t play in the first leg of the champions league after failing a late fitness test due to torn hamstrings and has already been ruled out of this Saturday’s trip to Real Sociedad and coach Zinedine Zidane is not expected to know whether he will have the 31-year-old back until the day of the City game.

Cristiano Ronaldo has scored 47 goals this season.
