Three seasons ago, John Stones was a highly-rated defender producing sensational performances for Everton.

Under Roberto Martinez, he was developing into one of the best young and consistent defenders in Europe with a bright future on the horizon.

But can he cut out the mistakes that lead to City conceding goals?
