Chelsea are the logical favourites in the Europa League final, but Benfica have great players.
I saw their two matches against Newcastle - they have an excellent defence and a lot of quality in attack, such as through Nicolas Gaitan and Oscar Cardozo.
Cardozo is a less creative player but has a great physical impact on opposing defences. He's never 'out' of a match and always plays with the will to physically 'kill' his opponent - the first little mistake made by the opposing defence and he will benefit from it.
Gaitan is superb individually and as a team-mate, able to score goals and pass with style. I consider this kind of player to be very rare these days - young players are now more standardised than they were before. It may be because fewer players start playing football in the street, leading to less creativity.
Benfica seem to have a privileged relationship with Brazil - all of South America in fact - and also Spain. They have always found fantastic, young Brazilian players [who do have that creativity].
Chelsea's experience in winning the Champions League final last year is an advantage for them, but this is a different Chelsea side.
Most notably they lost Didier Drogba and therefore huge experience, even though Ashley Cole, Petr Cech and Branislav Ivanovic also have this kind of experience.
The club changed its way of playing from being a physical side to a more technical team this year.
In the Premier League it has not been profitable for them as they dropped out of the title race quite early on. However, I guess that this team will go from strength to strength in the coming seasons: they have a technical trio in Juan Mata, Oscar and Eden Hazard - the latter injured for the final - who are very young, and other talents such as Ramires.
This team has shown in the Europa League that it has potential for the future.
