Benfica coach Roger Schmidt has warned Manchester United off Joao Neves.
The young midfielder is a January target for United.
But Schmidt is adamant there's interest in losing Neves midseason.
"I talk to them every day, all of them. We're in the middle of the season, we have big goals with Benfica," said the coach.
"Of course we're not going to let these players leave, we need them and they don't want to leave. There's no question about that."
