The Bayern Munich coach spent four silverware-laden years in charge at Camp Nou and in the process created arguably the finest club side of all time .
The 19-year-old currently on a season long loan at Everton, believes the quality of football Guardiola produced during his reign at Barcelona is impossible to replicate.
“Barcelona will never play like they did under Pep Guardiola ever again,” he said, in an interview with Four.
“Tata Martino is doing a good job but it will never be the same as it was under Pep.”
The Catalan prospect then opened up on how much he is enjoying his experience playing Premier League football and did admitt the atmosphere at games in England is way above La Liga.
“I feel fabulous,” he continued.
“I relish taking to the field in the Premier League. If I were a supporter I would pay good money to watch it.
“The passion of the fans in England is spectacular and, to be honest, Spain cannot compete with it.”
Deulofeu has made nine appearances for Everton this season, scoring only one goal.
