The Chelsea kids were in fine form in the Uefa Youth League last week, and Molde paid the price.
The Blues waltzed to a 10-1 win over the Norweigan side, continuing a run for the academy that sees them near the top at a variety of youth levels, all while the first team remains undefeated.
The academy also saw another success in the past week as Derby County loanee Mason Mount was called up for England's senior squad to face Croatia and Spain, after he made his Under-21 debut for the Three Lions in the last international break.
Here we take a look at the standout performers at Under-23 and U-18/19 level, as well as those who are currently out on loan.

The Blues made the semi-final of the competition last season - the deepest such run from any academy side in the trophy's history.
Thus far Newport County beat the Chelsea U23s in a heavy 3-0 win. Otherwise, Chelsea have drawn 1-1 at home with high-flying Leicester City and beaten West Ham 2-1 away in this period.

Under-19s & Under-18s
Chelsea's U18s have been dominant for a number of seasons, but last term they won the quadruple to set the bar even higher for the incoming generation.
