Valencia coach Unai Emery admits Miguel could be on his way in January.
Miguel is out of the first team at the moment and has been linked with a move to Aston Villa.
The decision is in Miguel Brito's hands," Emery said. "The only demand I make on my players is that they are fully focused on their football.
"The team needs Miguel, but until now if he has been giving 60 per cent and I need him to raise that to 100 per cent."
