I don't have the quotes of Brailsford's reasoning for hiring Leinders, but if all Porte is getting out of it is
“If you had a problem you went and saw him but to me he was no different to any other team doctor that we’ve had at Saxo Bank or Sky. When I was sick he helped me. I didn’t know anything about his past, I had no idea. I heard him talk about Rabobank once or twice but whoopee do he’s the ex-Rabobank team doctor. He gave me caffeine maybe but that’s about it. He gave me Strepsils and Paracetamol.”
caffeine, strepsils and paracetamol, then the whole "any GP who rides a bike a bit or works with athletes" would seem to have fit the bill?
Whoopee do indeed.
