On-loan at Bournemouth, Ake has capped strong defensive displays with two goals, including Sunday's dramatic winner against Liverpool.
"I compared him to Frank Rijkaard," said Michael Krul, who coached Ake for three years at the ADO academy, to the Daily Mail. "He was quiet off the field but a leader on it, a beast.
"He is very special, the most talented player I've coached. Great technical ability and a fantastic mentality. I've traced his career and he has the ability to succeed at a club like Chelsea. One coach must give him the chance because he can handle it."
