He endured a frustrating January transfer window in which Chelsea failed to bring in any fresh faces for the remainder of the campaign, with Lampard numerously stressing the importance of adding to his squad.
"I think hes a fantastic player," Lampard said. "He first came under my eyeline in their run in the Champions League last year. I thought he was one of their stand out players. We have played against him twice this season so I know a lot about him."
Lampard has been crying out for goals and creativity from midfield as Chelsea have struggled to replace the goals and assists provided by former star man Eden Hazard, and the Chelsea boss acknowledged that Ziyech can provide that quality.
"When you look at us this season there have been games where we have struggled to unlock the door and he is certainly a player we hope he can bring that bit of creativity, something different for us, scores goals, assists, so excited.
"I know he's not coming now but it's something exciting for us as a club and the fans to have him next year."
The 41-year-old admitted the club tried to bring Ziyech in during the transfer window last month, but says his focus is now on the future.
"We tried but it was not possible. We all know how the January transfer window works. You respect that clubs that have top players want to keep them but that's done and we will have him for next season."
