The teenage striker is being tracked by Arsenal.
Speaking to On The Bish podcast, England cult hero Heskey said: “I'd tell Keinan to enjoy it!
“My advice would be soak it all up and take in all the advice you get.
“He needs to enjoy his football. The sport, especially nowadays, you can take it too seriously.
“When I say that, I mean enjoy it as much as you can as well as seeing it as your job.
“It was fun for me. I loved it. I played with a smile on my face.
“It's also important to keep your feet on the ground and have the right people around you.
“My parents were great for that. I wasn't allowed to do certain things. I had a good network around me. I have the same friends now that I had when I was young.
“My advice would be 'this is your career, not someone else's, so look after it'."
