The pair struck up a relationship through the England youth system, with Alli enjoying life in the Premier League while Kiwomya develops his game in the Football League with loan-club Crewe Alexandra.
Kiwomya is a regular at the League Two club, but is looking to push himself to emulate the success Alli has had in the game. The two attackers are the same age and Kiwomya always knew Alli could do it at a higher level after seeing him play at MK Dons in League 1.
"I have known Dele Alli since I was fourteen. We are really good friends, best friends," Kiwomya told Goal . "He is the godfather to my child so he always tries to see him when he can. When August, my son, sees him on TV, he goes “woaaah.”
"I think with Del, it is amazing as I went to watch him when he was at MK Dons and he hasn’t changed one bit. 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.'"
Kiwomya is a quick winger and exciting to watch. On Fifa 17 he is one of the fastest players in the game, with a 93 stat for his pace and as a youngster he was among the fastest runners in England over 100m.
However, he does think that he has "more technical ability than Fifa's creators give me credit for."
The 20-year-old is from a footballing family with his uncle Chris Kiwomya having played for Arsenal, and his father, Andy Kiwomya, having played at a host of professional clubs. Alex Kiwomya himself has become a father recently and he admits that it has made him work even harder to keep making it in the game.
"[Being a dad] has massively, [changed my perspective] to be honest," He added. "It is hard but it is the best thing to ever happen to me. It has made me focus on football a lot more.
"I was focused before, but it is just now that I am providing for him that I need to make sure I am on it every day. I want to make sure that he grows up having the best things that he can have and that means I have to work my socks off to keep food on the table and a roof over his head."
The Chelsea loan star had short-term loan spells at Fleetwood Town and Barnsley ahead of his move to Crewe, where he scored and assisted on his debut in a 2-1 win against Stevenage Town. He went on to be nominated for his league's Goal and Player of the Month immediately upon his arrival.
Kiwomya is one of over 35 young players out on loan across Europe from Chelsea, but he has switched his focus to being a Crewe first-team player and has made 26 starts and 11 substitute appearances so far this season.
"People don’t treat me differently [in League 2] because I am a Chelsea loanee. Even the players at the club, they don’t look at me like that. They look at me as a player here to get minutes and I am here to get experience.
"Under-23 football is completely different to first-team football anywhere. The pace is so much quicker, it is just adjusting and getting used to it and I feel like I have done that. Three points matters.
"That’s the main thing, you go out and it is make or break. People are playing for their careers and their jobs. If you get relegated then it is going to be tough to get back up. It is a lot more physical as well. The players get stuck into you, I have had a couple of injuries. I had a dislocated shoulder a while back.
"Crewe are a footballing team. So are Chelsea. So you just have to keep to the roots that I grew up playing and that’s very good here.
"In training we pop the ball about and work on it. We don’t work on just long balls into a big striker so it is developing me also. It is always good to be at the top of the league and clear but you really test your will and how much you want it being that low [in the table].
"Some teams will fall off but we are climbing back up. I have got lots of minutes under my belt and that’s what Chelsea send you out on loan to do - to get minutes, goals and games under your belt.
"That’s what I have done here so it couldn’t be going any better."
Kiwomya counts his first professional goal as his best moment at Crewe so far, while he admits that he wants to improve his heading, despite already having a good leap on him.
Meanwhile, Alli is awaiting a huge FA Cup semi-final against his friend's parent club and Kiwomya admits that he doesn't pull his punches when he jokes around with the Spurs star.
"I always banter him a bit and then give him his praises when he scores. For the bad tackle [versus Gent], I gave him a bit but he takes it well. He is funny guy, a very funny guy."
Kiwomya's Crewe were competing for promotion but suffered a poor run of form and now have work to do to steer themselves away from a relegations battle in the final weeks of the season.
