I will review the content of 1501.03818 and 1511.05163. Top partial compositeness is a common feature of composite Higgs models. We study the case where masses for lighter quarks are generated through a different mechanism and we discuss the impact of the experimental constraints on the model, in a specific realization with a pseudo Nambu Goldstone boson Higgs. We show that there is no need for flavor symmetries is the up sector, while in the down sector a certain degree of alignment is required. We finally comment on model building aspects, introducing new physics sector with light top partners candidates, relating their lightness to 't Hooft anomaly matching condition.
