The 5 Spaniards on OFM-Quinta da Lixa are:
Gustavo César Veloso - former winner of Catalunya and a Vuelta stage. Started his career in Portugal, then spent a couple of years at Relax and Kaiku, then four years with Xacobeo-Galicía. Came back with Andalucía last year. On paper, easily the strongest of the five.
Délio Fernández - 3 years with Xacobeo, followed by 2 with Onda-Boavista before moving to OFM this year.
Alejandro Marque - a decade of riding, all with Portuguese teams. Bounces mostly between Loulé, Tavira and Boavista.
Eduard Prades - rode with Andorra in 2009, has been on the amateur scene until being picked up by OFM this year.
Jesús Rosendo - famously accused of biopassport violations then cleared due to haemorrhoids, Rosendo has spent his whole career riding for Andalucía - including the first half of this season, when he rode for their amateur team, before OFM signed him in July.
I'd say we're mostly clear of the days of Puerto rejects being in Portugal - of the Spaniards on Portuguese teams only Antonio Olmo has the likely stench of that on him (he was riding for Comunidad Valenciana-Kelme from 2004-6, then has been mostly amateur save for a random squad spot at the Colombian Boyacá es Para Vivirla team in 2009). However, we are not clear of aging dopers, as the likes of Nuno Ribeiro still being around attest (and of course Sérgio Ribeiro would have been here if he hadn't been busted again). With regards to the Spanish presence in Portugal, it seems that it has gone back to how it was pre-Puerto, i.e. riders, mostly those from Galicia and, to a lesser extent Andalucía (primarily in the southern teams, Tavira and Loulé), looking for a contract. Only while before they were looking for better salaries, now they're looking for the presence of a team, since Spanish cycling is suffering so badly in terms of number of squads. I will say it's disappointing to see a team like OFM, which is effectively a brand new team this year even if in reality it isn't quite, entering the Volta with more Spanish riders than Portuguese, however we should also note that the seemingly most successful Portuguese team - Efapel - comprises only Portuguese riders, save for one (Arkaitz Durán).
