Manchester City boss Sven Goran Eriksson says a shoulder injury won't affect Nery Castillo's chance of signing permanently from Shakhtar Donetsk.
Eriksson told City's website: "He is still young, we have him on loan for one year - not until the end of the season - he'll be here for half of next season. So then we'll see how he is. That's good for us.
"I think he's very happy to be here, he speaks Portuguese too, so he can speak to quite a few of the team already."
