Napoli coach Walter Mazzarri has called on his club's fans not to place a heavy burden on the shoulders of new signing Eduardo Vargas.
In a press conference ahead of Sunday's trip to Palermo, the 50-year-old admitted his knowledge of the Universidad de Chile hitman remains sketchy, but demanded supporters to give him a fair crack of the whip at the San Paolo.
"[We need to be] calm," said Mazzarri. "He is only young and has just arrived, [the fans] must give him time to grow and settle into his new surroundings.
"First impressions? He's a smart guy but I am yet to see him at work, having seen him on DVDs is something else. In a few days we will all have a better idea of him."
However, Mazzarri was contrasting in his assessment of former Bologna defender Miguel Britos, who is in the squad after spending the first part of the season on the sidelines, and forward Goran Pandev, who the coach expects to be an able deputy for the injured Ezequiel Lavezzi.
"I hope to have Britos available, we will see how he is in the afternoon," continued the trainer.
"I have faith in Goran, he is a great player. I hope he is in great shape and plays a great game against Palermo."
Kick-off at the Renzo Barbera is scheduled for 20.45CET.
