In an interview with O Jogo, Neto also identified FC Porto as his leading candidate for the Portuguese championship, praised midfielder Victor Froholdt and revealed that Benfica previously came close to signing him before he joined Wolverhampton Wanderers.
Neto said he follows Portuguese football when he can, although he does not support any of the country's leading clubs. He believes Porto have the strongest chance of winning the title, pointing to the continuity within their squad.
"Honestly, I'm not a supporter of any club in Portugal, but I would say the main candidate to win the title is FC Porto, also because of the matches I've watched them play. I know they were also very strong last year. They kept their manager and most of their players. That's another reason why I believe they are the main candidates to win the league.
"On the other hand, I watched Sporting and hardly recognised anyone. It's a new team, with a lot of young players."
The winger confirmed that he has not received any recent approaches from Portuguese clubs, but acknowledged that Benfica had previously been interested in bringing him to Lisbon.
"No."
That was his response when asked whether he had received any recent offers from Portugal, before being asked if there had been interest in the past.
"Yes, from Benfica. It's true, I was close to going to Benfica, but at the time I ended up signing for Wolverhampton."
Neto also believes Benfica have the potential to enjoy a successful Europa League campaign, praising their manager Marco Silva, whom he faced regularly during his time in England.
"I think Benfica can achieve something very positive in the Europa League, also because they have Marco Silva, a manager I like and who I faced many times in the Premier League. I consider him a very strong manager. Hopefully it happens. It would be fantastic for a Portuguese team to win a European competition. I would like Benfica, Sporting and Porto to be very successful."
Asked which players in Portugal had particularly impressed him, Neto singled out Prestianni, who has been producing an outstanding campaign for Benfica.
"It's impossible not to talk about Prestianni. He's having a phenomenal season, he also plays as a winger... and sometimes in the middle."
Neto has little doubt that the Argentine could adapt to the demands of English football, highlighting his work rate and ability to beat opponents one against one.
"Yes, he's a player who works very hard during matches, very strong in one-on-one situations, and he's scoring goals. It seems to me that he has all the ingredients to play in the Premier League.
"Besides that, Argentinians are normally well known for being combative players, which is important in this league."
Prestianni is not the only player in Portugal to have caught Neto's attention. He also praised Porto midfielder Froholdt, whose physical qualities and energy stood out to him when the two countries met.
"Froholdt, from FC Porto, also seems to be a great player. We played against Denmark and confirmed that he's a player with a lot of quality, very complete, physically strong, and he never stops running."
Neto's own future was also raised, with the Chelsea winger asked whether the financial opportunities available in Saudi Arabia held any appeal.
His response was unequivocal: his commitment remains with the London club, having recently renewed his contract.
"I'm attracted to Chelsea, the club with which I renewed my contract. My head is only here. The club has looked after me, given me everything and I'm very grateful for that. I don't think about other scenarios."
Neto's assessment of the Portuguese league therefore offered encouragement for Prestianni and Froholdt, while making clear that his own ambitions remain centred on Chelsea rather than a move elsewhere.
