Match Reports
Abraham had appeared to put the hosts in total control of the tie with two early goals, only for Jordan Clark's strike on the half-hour mark, with the aid of another Kepa Arrizabalaga error, to give Luton hope of a shock at Stamford Bridge.
However, Abraham was on hand to ease any home nerves with a close-range finish 16 minutes from time and despite Timo Werner missing a late penalty, Chelsea still set up a fifth-round clash at Barnsley.
