Recent measurements at the Large Hadron Collider have shown that p+p and p+Pb collisions exhibit flow like phenomena, such as long-range rapidity correlations, and strangeness production enhancement with the charged particle multiplicity. These effects were already observed in large collisional systems i.e. heavy ion collisions, and interpreted as evidence of the creation of a hydrodynamically evolving fluid, the quark-gluon plasma. These striking similarities has lead to an intense theoretical effort to understand the origin of the collective-like phenomena in small collision systems. In this talk, I shall present the phenomenological consequences of considering correlated constituents inside the proton on the initial state properties of p+p interactions at LHC energies.
