The 27-year-old joined the Magpies for only £5million from Stoke City in the off-season and has already scored after playing three Premier League games for his new club.
The Spaniard believes he is probably worth more than his transfer fee suggests but isn’t too concerned about it and simply wants to work hard for Newcastle.
“Newcastle bought me, and now I am trying to play well and trying to help the club win games,” said Joselu, as quoted by the Northern Echo.
“It doesn’t matter if I cost £5m, £6m or £25m – the transfer market is crazy now. I don’t care about that.
“I’m just hoping for an opportunity now. I think I have played well, and I am trying to work hard every week to make sure I can be on the pitch and try to score goals to help the club.”
He added: “Rafa is a big manager in the world of football. When he talks about you and says he has followed you, it’s nice to know. I am very happy to be working with him.
“Rafa told me to sign here, he told me many good things about the club, the city, everything. I didn’t have to think too much about it. I signed quickly and I am pleased I am here.”
