The west Londoners advanced into the competition’s fourth round courtesy of goals from Mason Mount, Timo Werner, Callum Hudson-Odoi and Kai Havertz.
However, it was Ziyech, that especially caught the eye of the Blues boss in the encounter.
‘Talent and guile among lefties’
Ziyech’s wand of a left foot has seen him draw comparisons to a host of creative Chelsea predecessors.
When responding to the attribute, Lampard suggested it was a ‘talent’ common among left-footed players.
According to the Englishman, they possess more ‘guile’ than that of their right-footed counterparts.
“It’s a talent and typically it seems like lefties have that little bit more guile with it,” Lampard said.
“I don’t know whether that’s right but we’ve always seen that over the years.”
‘Very happy for Hakim’
Though not on the score-sheet, he provided the assist for Hudson-Odoi’s strike, Chelsea’s goal third of the match.
He was also involved in the build-up to Werner’s goal and created an opportunity for the German, prior to the forward’s eventual finish.
Lampard admitted Ziyech fails to complete some of his passes on occasions. But he admired the intent and confidence of the player to attempt such a skill.
“He sees the pass and has the confidence to take on the pass. He might mishit, overhit or underhit some, but he’s looking for that vital pass and not always from wide, from central areas as well.
“I’m very happy for him to get in there.”
The Moroccan has had a difficult start to his Chelsea career, with knee injuries delaying his competitive debut. But he has excelled when fully fit.
The 27-year-old has been involved in six goals from 14 games in all competitions. These include two goals and four assists. Five of those came in a four-game spell between late October and early November.
Ziyech had sustained an injury in December and missed five of his last six Premier League matches due to injury.
However, with another attacking return to his name, he will take confidence going into Friday’s fixture against Fulham.
