Hbb associated production is often advocated as an ideal proxy to measure the bottom-quark Yukawa coupling yb. However, large irreducible background exists, which make the extraction of yb very challenging, if not impossible. I will discuss some recent calculations which showed how gluon-fusion, VH and VBF production conspire to kill our sensitivity on yb from Hbb at the LHC.
