			I barely know anything about cycling (just interested in this subject), but Dr Ferrari is the most discredited pariah in the sport is he not?
If there was credible evidence that Bradley Wiggins was "using" him then, he'd be out of the sport and publicly shamed in a trice, surely?
		
		
	 
No. What you have to understand is this when it comes to national heroes (Armstrong, Contador, Wiggins etc) :
Only acceptable evidence is a positive test.
When there is a positive test - the testing procedure is flawed + the test was triggered by too much beef/whisky/sex delete as applicable.
When there is eyewitness testimony - it is from bitter jealous people.
When there is documentary evidence - it was a misunderstanding and they never actually met the doctor concerned.
When there is indirect evidence - links between people, etc - it is all in the imagination of people.
So, just as Contador fanboys claim that there is no evidence of him working with Ferrari or Fuentes, Armstrong fanboys claiming he never tested positive, Sky fanboys will scream 'no evidence', just like the others did previously. 
The evidence/suspicion is:
Froome's and Wiggins' improvement - Armstrong had a WC and a couple of decent 1 day race results before 'post-cancer weightloss and cadence' transformed him.
The number of people involved in/implicated in doping at Sky within the senior management and riders. The improvement in Sky's road performance from their first year seems to map onto their coming on board. Again, Armstrong hung around with Hog who was well known for his love of PEDs, Contador's ridden for Saiz, Hog, Riis. 
Training in Tenerife - of all the places in the world you choose a place that is notorious for being a favourite of dopers. Even pre-USADA it was known that Tenerife was a favoured location for riders suspected of doping to go to dope/charge up etc. (Since confirmed by the USADA evidence). But again, when this was pointed out to the Armstrong and Contador fanboys - it was dismissed as 'not evidence'.
'No evidence' is something of a red herring, because most fanboys of any rider, will never accept any evidence against their heroes. If Wiggins were to **** hot tomorrow, you can bet that the Sky apologists will be out with excuses to explain why this happened and why Wiggins is clean. 
Sadly, for some people, cycling takes on a cult like tendency as they refuse to accept that their heroes are fallible and anyone saying otherwise, is automatically a heretic or a talibani, bitter, jealous (delete depending on your chosen way of insulting critics).
