Rafinha believes Barcelona new head coach Luis Enrique will go on to be a resounding success at Camp Nou without stress.
The Blaugrana were humiliated last season - and they couldn't secure any silverware, despite being so close to winning the Copa del Rey.
Coach Gerardo Martino thought it wise to resign after he couldn't defend the La Liga title on his debut season - and the club were quick to secure the services of their former player, Enrique.
Having worked with the 44-year-old new manager when he was on loan at Celta Vigo, Rafinha is adamant that Barcelona can recover from a disappointing campaign last time.
"He's a coach with clear ideas, he'll succeed easily," he is quoted as saying by AS.
"The group is very easy to get on with. They're good people, very good people. They want me to perform well and prove myself physically.
"[Pre-season in England] serves to take us to the physical level we need. This climate is perfect for pre-season because it's very hot in Barcelona.
"The faciilties are incredible, among the best in the world."
