The pair won the FA Youth Cup together at United before Keane eventually left for Burnley.
Keane said on YouTube: “Yeah still friends.
"I've known Jesse since I was 10 years old. We've been all through the academy together, we had our first loans together at Leicester, and with England together, so whenever I go to England and he's there it's like we've not been apart.
"He's still one of my best friends there… He's such a good guy. He's just funny and down to earth – he's a top lad."
