I have met several footballers complaining of pain in their shins, knees, ankles, and hip joints. In fact, I suffered from pain in my joints for years. After spending months and a lot of money on physiotherapy and medication, I found out that I had been making one big mistake. It has nothing to do with diet. It has nothing to do with training either. The real problem was football studs.

Most footballers (excluding professionals) play and train on hard grounds without any grass and high-quality turfs. Football studs don't provide any cushion, putting a lot of stress on their joints, which causes pain. Now here's the solution: Football trainers. Trainers not only provide cushion but also give you a better grip on hard ground. As soon as I replaced studs with trainers, my joint pain was gone. 

Now here's a pro tip. If the budget allows, I recommend you buy a set of football studs and trainers of the same brand, same model, and same size. This will allow you the flexibility to switch your footwear seamlessly according to the surface. You can wear trainers for training and studs for matchdays. This worked for me, and I am sure this will work for you as well.
