Barcelona confirmed Valverde as Luis Enrique's successor yesterday, with the Spaniard leaving after three successful seasons at the Nou Camp.
The former Athletic Bilbao manager will take charge of a team packed with superstars, but still reeling from losing out on the La Liga crown to fierce rivals Real Madrid.
Despite dominating European football over the last decade, many feel Barcelona are on the decline.
And reports in Spain are saying that Valverde is preparing a huge overhaul of his new squad to ensure they challenge Real for both domestic and European prizes next season.

“It’s clear that, the more I play, the better,” he said.
“My dream has always been to play here and stay at Barcelona for a long time.
“We haven’t spoken about it, but a footballer always wants to play and I have not played as much as I’ve wanted to.”
