Liverpool defender Joe Gomez credits Paul Hart as a big influence on his career.

Hart worked with Gomez at the Charlton Athletic academy.

"He threatened to not let me play until I sorted the heading," said Gomez to the Daily Mail. "If it wasn't for him I may not be here. He wasn't shy about telling me. Everyone in my team knew about it!

"There are times when I found the criticisms difficult but they were the best thing for me.

"It wasn't just football. The way you conduct yourself, rules and attitude.

"Heading definitely wasn't my best attribute and my body language showed that. So I just had to change. Now I thrive on it. Back then I wasn't how a proper defender should be."
