Departing Chelsea boss Guus Hiddink has again told his eventual successor that the current squad needs an injection of youth.

"The older players showed they can still perform very well and it is good to have a strong squad," said Hiddink.

"If you play 60 games a year, plus internationals, you must have the possibility to rest people.

"But it is beyond question that when older players get injured, it is harder for them to come back at the highest level."
