Either him or Patsy Parisi. Most likely Carmine, he is still in some way or another apart of the Lupertazzi Family and will have to remain loyal. Phil would have had him killed by now if he wasn't. As for Patsy, he's never liked Tony since he had Philly killed and gave Chris the vacant Capo spot even though Patsy had senority. Though I think both will be dead when all is said and done.
