Timo Werner broke his 12-game goal drought as the Blues cruised past League Two Morecambe 4-0 in Sunday’s FA Cup third-round clash at Stamford Bridge. Mason Mount, Callum Hudson-Odoi and Kai Havertz were also on target in a facile Chelsea victory, where boss Lampard fielded a potent line-up to boost confidence.
