In the basement of Old Trafford is the official team shop. It's one of the world's most popular team shops in the world. You can buy a souvenir of the "Red Devils", be it a Cristiano Ronaldo shirt, or a different garment (hats, scarves, pants, jackets, coats, socks) ... Recently, Manchester United has been one of the most successful teams in the world, and they've taken advantage of this to improve their marketing and invest more money in the team. It's clear that this has been successful based on the shop. Although for me the products on offer at Liverpool were cooler.
