Well, I mean, Deidara alone is kinda uncomfortable opponent for Itachi after their last battle in the series, since Deidara already took some measures to avoid being defeated again - C4 is still in play, Deidara's left eye can still see through genjutsu, and Itachi cannot use Lightning Release, thus having no elemental advantage against him, unlike Sasuke. So with Sasuke's abilities, his struggle against Deidara isn't really a feat, he never was a genjutsu specialist and possessed lightning techniques capable of defusing Deidara's bomb, while it's a vise versa in Itachi's case. Sasuke was a way too reckless, he could've avoided any problems with Deidara if he took him seriously from the very beginning. Possibly, Itachi could take on that Deidara and defeat him, albeit with great problems, but adding Sasori into the fight would leave Itachi almost no chance of victory.
