Lukaku seals for-sale Chelsea's FA Cup win

On a seismic day in the history of Chelsea Football Club it was perhaps fitting that Romelu Lukaku, their record signing, scored the winning goal in a 3-2 FA Cup fifth-round victory at second-tier Luton Town.

For most of a damp Wednesday evening at Kenilworth Road it seemed the European and world champions were going to suffer a humiliating exit, hours after Russian businessman Roman Abramovich announced he was putting the club up for sale.

Saul Niguez levelled after 27 minutes but an intrepid Luton side restored their lead before halftime as Harry Cornick beat Chelsea keeper Kepa Arrizabalaga.

Luton looked capable of holding on for a giant-killing but Werner equalised in the 67th minute after being picked out by a lofted pass from Ruben Loftus-Cheek.

Chelsea dominated the second half and Lukaku, out of favour of late despite his near 100 million-pound ($A183 million) price tag, had the final say as the London side moved into the quarter-finals.
