2. Kurt Zouma (Chelsea):
Kurt Zouma moved to Chelsea from St. Etienne as a talented young defender with the right attributes – power, strength, bone-crunching tackling ability – but needed time and space to develop into the finished product. Glimpses of his talent and his mental strength were seen last season, when Jose Mourinho offered him a chance to play ahead of Gary Cahill, when Cahill was out of form, in games against their major rivals. After that, he was moved into defensive midfield, when Chelsea needed to shut games out.
With the possible arrival of John Stones, he might be shifted into defensive midfield as cover for Nemanja Matic, and will play a role at the back if required, as Chelsea need to build their squad depth defensively.
