"I will always have a little moan because it would have been nice to score more goals for the amount of possession we had," he told the official Chelsea website. "I thought we played better stuff than the first leg last week, when we were a bit frustrated with the fact we were just passing around with no purpose.
"We were unlucky to hit the woodwork a few times but we had some excellent passages of play, some really nice interchanges and quick one-touch passing."
Morris rated Reece James as best afield.
He added: "Marcel Lavinier did well playing his first game at the Bridge but I felt Reece James was outstanding, head and shoulders above anybody on the pitch."
