Well, players look good all the time when playing at lower level tournaments.
Well, excuse me, Verratti is already great and has the potential to develop even further, but the French Ligue 1 isn't world's toughest, nor greatest league. One-horse race similar to German Bundesliga, Bayern and Dortmund, compared to Olympique Lyonnais and PSG domination this century.
I know some of you here worship Marco Verratti, but calm down, it won't be an immediate effect, there is a slight chance the transfer of not even happening. Anyway I expect more of a Modric type of development - slow but steady development. Real Madrid reap the fruits of their patience, the Croat is their MVP, their Xavi and will never get the Balon d'Or thanks to his "world's greatest player for the past 20 years" teammate, who actually cannot even dribble with the ball any more.
