Opening of the Sharingan Eye (Target: User) [HELP PLZ]

[undeadjebus]

A team sent out to attack consists of:
(Healthy/Head Ninja) N-203 Itachi Uchiha
(Healthy) N-383 Sasuke Uchiha

They are blocked by a team that has the same power.
Sasuke plays J-131 Chidori.
Opponent passes priority.
Itachi plays J-365 Opening of the Sharingan Eye, targeting Chidori.

Does the "Target: User" apply to Itachi and Itachi also get's +5/+0 or does Opening of the Sharingan Eye fail and Sasuke is the only one that get's the +5/+0 causing the battle to end in a draw and Chidori doesn't get it's secondary effect?

I did look through the threads with the search function but couldn't find an answer to that type of situation.
