Kiwomya, 20, is currently out on loan with League Two outfit Crewe Alexandra.
"I respect him so much for that. Even the way he plays - he hasn't changed the way he plays. He is just with better players now.
"He is just absolutely blowing everyone away with what he can do. I had no shadow of a doubt in him and we are always speaking to each other about football and what's going on.
"We like even just talking about personal stuff, it is nice to know that even though he has got all those England caps, all those big goals. He is just Del, he is just the same guy.
"I want to play in the Premier League, one day [like him].
"It is going to take a lot of work and dedication. I have got that so it is just keeping at it and when I get the chance to impress someone I have to make them think, 'I will take a chance on him and I will take him in and see what he can do.'"
