Blackburn Rovers, who knocked Coventry City out at the Fourth Round stage, were heavily beaten in the opening leg of the FA Youth Cup Final against Chelsea at Stamford Bridge.
Chelsea, who were beaten by the Sky Blues earlier this season in an Academy League fixture, scored twice in the first half through Nathaniel Chalobah and Baker.
In the second half, Feruz, who has been called into the Scotland U21 squad, hit a brace to give Chelsea a 4-0 lead to take into next week's second leg.
