First soccer game win - need advice on managing expectations

So 5yo had his first real soccer game last weekend and his team won 3-1. He scored once (honestly don't know how but I'll take it). Now he thinks he's Messi and wants to practice every single day. This is great but also I'm exhausted lol. How do you guys keep it fun without burning them out? Don't want him to lose the passion but also... I have other stuff to do sometimes
