Napoli coach Rafael Benitez has set a goal target for new signing Michu following his move from Swansea.
The 28-year-old joined the Italian club from the Swans on Thursday evening on a season-long loan, with an option to make the deal permanent next summer.
The former Oviedo and Celta Vigo player struggled with injuries last term and scored only two goals in 15 starts in the Premier League.
But Benitez told a news conference: "Michu is a player that can play in two positions. He can play as a striker or as a lone forward.
"He is able to penetrate and score but also knows how to play with other strikers.
"I have told Michu that I expect a certain number of goals from him just to motivate him but he first has to adapt to the team and get to know his new teammates.''
Michu joined Swansea from Rayo Vallecano for 2.2 million pounds two years ago and was the club's top scorer with 22 goals in his first full season.
He is under contract with the Swans until June 2017.
