Is Man City the richest club in the world?

Could you please elaborate on the basis for the claim that Manchester City is the richest club in the world? Are we considering their overall financial assets, revenue streams, or perhaps the value of their player contracts? It would be interesting to know if there are any other clubs that could potentially rival or surpass Man City in terms of wealth, and what factors contribute to their financial success. Additionally, how does the club's financial status impact their ability to attract top talent and compete at the highest level of football?
