I don't think Alonso was ever afraid of Perez as a teammate, but I'm starting to think Ferrari wanted Perez but knew they couldn't have him because Vettel is coming a year later - so, aware of his talent, they said he was too inexperienced in the hope that interest from other top teams would be diminished. Perez is now a serious threat, and Alonso isn't wasting any time playing mind games with his newest rival.
