What does Christian vs Alberto Del Rio mean for Summerslam?

Hopefully you guys remember when Christian won his first World Heavyweight Championship. It was at Extreme Rules in 2011.  But do you remember who Christian faced in that brutal Ladder match?  It was none other than Alberto Del Rio.  These 2 guys obviously have a lot of history together. Do you remember how the rivalry started?  Well it started when Alberto Del Rio broke the arm of Rey Mysterio.  Christian was Reys best friend so Christian went after Del Rio because he was furious....but Alberto Del Rio broke Christians arm too.  Then Christian would return at Elimination Chamber in 2011 and save his best friend Edge from getting attacked by Alberto Del Rio.  Then Edge was forced to retire and now a few years later we look at Christian as one of the best in ring performers currently in the WWE.  So what will happen at Summerslam.  Will Christian be able to hit the KillSwitch on Alberto Del Rio or Will Del Rio break Christians arm again?
