On the signing criteria issue, here's your Abarcá Sports name 'n' shame list since Puerto. I have limited it to riders who've had a +ve/ban or who have been expressly named in a doping investigation. This has not included those where some initial names have come out and then everything's died down and nothing is ever mentioned again (eg Daniel Moreno) but has included those where names have been released in more formal ways eg Tino Zaballa in Puerto. Also, I am only looking at riders where this happened either at Abarcá or before they moved there (so not the likes of Antonio Colóm or Marlon Pérez who were long gone from Egüés before they tested positive):
POSITIVES OR BANS
Rui Costa* (2009-13) - methylhexamine, June 2010 - ban overturned after contamination proven
Marco Fertonani (2006-7) - testosterone, February 2007 - last upheld positive for an Abarcá rider
Christophe Moreau (2010) - anabolic steroids, March 1998, EPO, July 1998 - 6 month ban
Óscar Pereiro* (2006-9) - salbutamol, July 2006 - TUE applied
Alejandro Valverde (2005-10, 2012-13) - Puerto (ban 2010-11) - evidence predates time at Abarcá although unlikely no Fuentes link 2005-6.
Francisco Ventoso (2011-13) - furosemide May 2008 (with Andalucía-CajaSur) - 9 month ban
Giovanni Visconti (2012-13) - Ferrari contacts, banned Oct 2012-Jan 2013.
RIDERS NAMED BUT NOT BANNED
Rubén Plaza (2001-3, 2007, 2010-13) - Puerto (rode for Abarcá post-Puerto)
Constantino Zaballa (2006-7) - Puerto (rode for Abarcá post-Puerto)
*though positives, no ban applied/ban quashed. This could also be applied to the first Moreau positive, however the second for EPO was upheld and therefore no asterisk appears by his name.
