Ben Chilwell and Thiago Silva have followed them through the door, with a deal for Kai Havertz still thought to being worked on, but they were not involved in Saturday’s 1-1 draw with Brighton.
Werner got himself on the scoresheet. Ziyech played the ball forward to Callum Hudson-Odoi who knocked the ball down for the Germany international to get himself a first goal in a Chelsea shirt.
And Lampard showered both players with praise for their displays.
‘I thought Timo was really sharp and bright,’ said Lampard.
‘He got his goal really early in the game, he showed some of the qualities that I know very well he has so I am very excited about having him in the squad.
‘I thought his work rate and everything about him was a great little start for him and Hakim Ziyech the same, some of his contributions and passing and quality levels were great.
‘He has a bit of a knock on his knee, a little bit of a small twist which we will have to assess, hopefully it is not too bad, but in the performances they were both really good.’
Lampard was left satisfied with his team’s efforts, particularly given Brighton are further along in their pre-season preparations.
‘For the players, the fitness level we are striving for before, now a lot go away on internationals, so it was part of our pre-season plans as such.
‘I thought the first half was bright and fresh considering where we are at with those levels, against a good team, so it is not so much the result, we obviously want to win every game, but to see individuals getting fitter, the collective as a team, it was a pretty good day for us.’
