If he doesn't make a good start, patience will be in short supply.
Valverde arrives at Camp Nou after four years in charge of Athletic Bilbao.
HAVE appointed Ernesto Valverde as their head coach on a two-year deal, with an option for a third.
Ernesto Valverde was officially unveiled as Barcelona's new manager on Thursday.
Valverde also had a two-year spell as a Barcelona player in the late 1980s and will now return to the Camp Nou after a 27-year absence. He has formerly managed in the city before during his time with Espanyol, another club for whom he also played, and has tasted success overseas across two spells with Olympiacos in Greece.
His serious, even-keeled demeanor should help him handle the high-pressure atmosphere surrounding Barcelona that left Luis Enrique in need of a long break.More news: Apple unveils the newest version of macOS High Sierra at WWDC 2017

One of the factors which helped Valverde land the job was that he knows how the club works, having spent time playing for them nearly 30 years ago.
"I don't think that Barca moved away from their style under Luis Enrique, I followed them recognisable. I don't know many players who were born millionaires".
"To say what can be improved is a unsafe thing and I can only tip my hat to what my predecessor Luis Enrique, who is a great coach, achieved here".
"It's the most hard challenge in my career but also the nicest". He said he plans to "have a fluid relationship" with the reserve team. "He promotes players from the youth teams and he has a style and a way of working like ours", he said.
The president, however, said Enrique's last season in charge, which finished with only the King's Cup in the trophy cabinet, was a disappointment.
Valverde will now be making the jump from Bilbao's homegrown squad to Barcelona's collection of stars.
Moreover, Valverde's calm and composed nature was favoured by the Barca board over the more fiery approach of the other leading candidate Jorge Sampaoli, who is expected to leave Sevilla to take over as Argentina boss.
"We idealise too much all this, millionaire players and all that".
