If the Flash were to fight Goku, he would immediately have the upper hand. Goku might be fast, but with the Flash's connection to the Speed Force, he can turn any battle to his favor. He could even drag Goku into the Speed Force, where he would be much stronger and finish off his anime foe.

Is Goku stronger than the flash?

Goku does have the power advantage, his fights have proven he can take on universal level threats before, so don't think that Flash is more powerful because he isn't. Gogeta: Goku can keep up with Beerus, and both of them could have destroyed the entire universe if Goku didn't pull off some plot induced stuipidity.
