Covenent Found but what did Camrose Estates agree to?

So finally a copy of the Covenant has been found, which states nothing can be built on the ground, which should remain a football or sports ground.

Whatever Razzak is and there’s lots of words that fans would call him, he is not a stupid man!

My question in all this “Why hasn’t someone asked Camrose Estates, what they agreed to when they sold the Freehold” to the greedy multi-millionaire. Surely, they could confirm the situation with regards the covenant?
