Former Napoli midfielder Allan has enjoyed his first season in England with Everton.
He has settled in to life in England quickly and recently revealed that he "didn't have to think twice" about signing for Everton because of Carlo Ancelotti.
"Working with Ancelotti is fantastic. To work with someone who has won all the major trophies is marvellous," he said.
"You learn a lot from him every day in training. I'm really proud that a coach of that pedigree, who has had such a career, likes me and admires my football.
"Hopefully together, here at Everton, we can achieve the things this club deserves."
