Veiga says Sporting's record of producing outstanding talent from their academy sets them apart in Portugal and across Europe.
He told Chelsea's website: "They are the best in the country, if not the best in the entire region. That's why you can see that the quality of players in Portugal, which is a small country compared to Brazil and other countries, is fantastic.
"It is a product of the academies when you are very young."
On working on becoming a first-choice at Chelsea, Veiga also said: "I want to do my best for this big club and win a lot of trophies. That's what we all want.
"We don't know if it's today or tomorrow, but that's our primary goal and that's what we're working towards."
