Messi already has four goals from three appearances in La Liga this season, claiming a brace and two assists in an 8-2 demolition of Huesca on Sunday.
The former Brazil striker said "transparency" and "competitiveness" will be part of the basis of his management.
Barcelona have flopped on the European stage by their own high standards in recent years, with their fierce rivals scooping three consecutive Champions League titles, led by Cristiano Ronaldo's incredible goalscoring feats. Because of last season, he finally received the recognition he deserved, as one of the best players in the world.
"It is necessary because we have had three years where we have gone out in the quarter-finals and the last was the worst of the lot due to how it happened", said Messi. "Now he's the captain, the leader and he wants to lift trophies".
Ronaldo also features, for his overhead kick for Real against new team Juventus.
One criticism levelled at Real Madrid in pre-season was that they failed to adequately strengthen their squad, though the same can not be said of Barca, who brought in Clement Lenglet, Malcom, Arturo Vidal and Arthur.
Messi's World Cup wasn't great-though his team made it just as far as Ronaldo's, yet he only scored once and missed a key penalty-but his year as a whole, as defined by the range voters are supposed to focus on, was tremendous.
"You've seen in the first few matches of the league season that some players who were a little inhibited before are now at a good level". Here's a look at what it is, and who he's going up against.
"We can not complain about the player who have arrived", he stated. "They're humble, hard-working and keep their heads down".
"Apart from Arthur they all come from Europe, and Arthur and [Clement] Lenglet are the ones who have been the most surprising. But, yeah, this is a thing that I'd like to be better at".
Also linked with the club in the window were Frenchman Paul Pogba and Antoine Griezmann, and Suarez was asked about them as well.
"Football is played on the field and that's where Cristiano won", Mendes told Record.
"Each year the competition is more even with clubs investing more money to compete and bring in players".
