“I have come with high expectations but also willing to work very, very hard and so far it has been good," Sandro said.
“I have had a lot of support from team-mates, from Ronald Koeman and the technical staff but I know, coming from a different league, it is hard to adapt but I came with a very, very open mind and willing to work very, very hard.
“I think I will adjust quickly."
He added: “It is a different game here, in Spain teams have the ball a bit more, at a lower tempo and it is a bit more tactical.
“Here it is more physical, there is more intensity but I think my characteristics will adjust perfectly for the Premier League and, as I say, with help from the technical staff and my team-mates, the league is perfect for me."
