The author of the McLaren report into doping in Russia admits "nothing surprises me anymore" on the day he revealed evidence of "corruption on an unprecedented scale". 

Professor Richard McLaren admitted to beIN SPORTS that there are "hundreds" more urine samples at a Moscow anti-doping centre which he would have liked to check. 

The IAAF banned Russia from competing at the Rio Olympics & McLaren believes the decision was justified in light of the evidence they were provided. 

McLaren has urged sports governing bodies to stop infighting and work together.
