Well I dont believe everyone believes Neymar is better that Ronnie at the same stage in their career to directly counter what you just said. But I respect once again your previously highlighted style is 'anyone' or 'no one' and I accept your need to exaggerate and yet to be 'honest' too.
Secondly, in answer to your question. The most difficult games in my opinion (warning just to reiterate, this is my own opinion and I am not replying to what someone or anyone said on this thread or anyother..) is competitive internationals. I have watched many games in the Brasileirao on TV and at the stadiums and the defending is atrocious as it is in international friendlies where Neymar has flourished and been given a massive amount of games - correctly so - also my opinion.. So I judge international competitive games.
At 22 Ronaldinho had 6 goals in the confed cup and 2 world cup goals - (one match winning against England in the quarter final (Brazil won that WC)). He also scored in Brazil's victorious Copa América Championship campaign. He also had assists in these tournaments.
Neymar is over half a year away from being 22. So far he has 2 goals in the copa america and no assists and no trophies of the tournaments Ronnie had. So just 2 competitive goals for Brazil....However he has many goals in friendlies including 3 against china, 1 against Iraq, 2 against Japan, 1 against Costa Rica 2 against the USA and 2 against scotland to name a few and all these have been friendlies just to repeat. That is already over half of his total goals for Brazil. He has also scored against far better teams but as you can see, only in friendlies besides the 2 copa goals. The good competitive defences in serious games mark him out quite effectively. This however does not mean he wont be a billion times better than Tello (no one said that exact statement or denied that exact statement, I am just making it by myself).
