Jennings has just returned to football at non-league Runcorn Town.
"I left Liverpool when I was 15 after being there for eight years, and a lot of people didn't see me coming back. I came back stronger, went to Tranmere and the rest is history.
"So I've been written off before and I've been written off again. For me, that just adds fuel to my fire. I love to prove people wrong and I want to do it for my family. I'll give it everything I've got."
