There are numerous places where Jesus made statements alluding to His deity. Here are just a few from the Gospel of John:
John 5:18
John 5:22-24
John 8:57-59
John 10:30-33
John 12:44-46
John 13:12-14
John 14:6

In John 10:30-33, notice the crowds' reaction to what Jesus says...

“I and the Father are one.”
The Jews took up stones again to stone Him.
Jesus answered them, “I showed you many good works from the Father; for which of them are you stoning Me?”
The Jews answered Him, “For a good work we do not stone You, but for blasphemy; and because You, being a man, make Yourself out to be God.”
