Be more specific.

Javier Pastore
Steven Defour
Milan Badelj
Jack Wilshere (possibly)
Eden Hazard
Paulo Henrique
Like for like, probably Markus Henriksen is the best fit.
Luka Modric
Paulo Henrique
Javier Pastore
Javier Pastore is a good player and great replacement for lampard(I always signed him).However he is a diffrent player and he has his game style ;)
I got Pastore to replace him, however Pjanić couldn't be wrong either. Maybe Josh McEachran :)
Hamsik, Pastore, Pjanic, Wilshere.

Hamsik is the best option imo.
Marek Hamsik. Pastore is amc, who lacks the position, teamwork and workrate the MC position
