At 38 years old, many footballers would have been written off by now, and that's if they hadn't already retired.
It's very rare for someone in his late thirties to still be playing at the elite level of football. In the nicest possible way, Thiago Silva can be described as a freak.
That can only be testament to how he conducts himself on and off the field. Many managers have stated their admiration of Silva and how he works tirelessly behind the scenes to ensure he remains at the level he is right now. It's no easy feat.
