Former Chelsea technical director Michael Emenalo said defender Andreas Christensen is a prime example that the club's loan system works.
Asked about the club's loan programme and whether Christensen is a good example of the working being done, Emenalo — who stepped down from his position on Monday — told Chelsea TV: "Absolutely.
"Andreas, unbeknown to him, gave me a wonderful parting gift yesterday because his performance is indicative of what development is all about.
"Development equals humility, hard work and timing and Andreas has done all three.
"He's shown great humility to go on loan and work very hard while he was there and gain the experience which is needed.
"The timing is right for him now to step in and show what he's learnt during those periods of development."
