Steve Millar of the Daily Star said the winger now has an astonishing £45 million buyout clause in his latest deal, as the elite clubs in Europe desire his undoubted talent. Guedes is said to dislike the comparison to his iconic international team-mate, but he became Portugal's first 18-year-old since Ronaldo to make his full debut for his country.
Guedes also became the youngest ever Portuguese goal scorer in the Champions League when he hit a magnificent winner in an away match at Atletico Madrid at the start of the campaign, per Millar.
The player's audacious finish was captured on video:
BeIN Sports USA reporter David Cartlidge said Atletico had "no answers" for the winger in their first Champions League meeting against the Eagles:

Interested to see how Atleti cope with Guedes tonight. Had no real answers for him in first meeting with Benfica. Movement took them apart.2015-12-8 19:39:23
The 19-year-old appears destined to become a superstar, and Benfica have been wise to insert the gigantic buyout clause in his latest deal.
However, if Guedes continues on the same trajectory of development as he has in the past 12 months, the price of £45 million could represent significant value in the very near future.
Clubs will not be afraid to bid huge sums for the world's best young talents, as United's £36 million swoop for Anthony Martial in the summer proved, per Jamie Jackson of the Guardian. Martial is only 11 months older than Guedes and has already proved a hit at Old Trafford in the Premier League, as his price tag quickly fades from supporters' memories.
In other news, Radamel Falcao is likely to remain at Stamford Bridge until the end of the season after Monaco admitted they do not want him back at present.
Monaco vice president Vadim Vasilyev told the team's DailyMotion page (h/t Rhys Turrell of the Daily Star) that the Ligue 1 club have no interest in ending his loan at the Blues: "We have decided not to take him [Falcao] back to Monaco for the moment."
As the reputation of Falcao collapses after his injury problems, the status of Guedes grows. The youngster is one of the most exciting talents on the planet, and he has a maturity beyond his years.
A move to England would severely test the teenager, but Ronaldo's switch to the Premier League was the making of him, forcing the attacker to develop his physique and learn to take punishment from defenders without letting his personal standards slip.
Guedes would be a capture Chelsea could build a dynasty around, as the current crop of attackers at the Bridge have seen their usefulness decrease since winning the title.
The next full-time boss of Chelsea will desire a red-hot talent at his disposal, and the Portuguese whizz-kid could be the answer to Blues supporters' dreams and aspirations.
