I can't begin to understand how Messi would feel.

Who?

he lacked the ambition to test himself elsewhere which might hinder his growth and he won't be able to get the recognition that his talent truly deserves.

I said the exact same thing in reply to another article. He can only ever be considered the best when he's playing against the best every week. And by playing against the best, he'll improve.

£250m is a lot of money.
