We study the effects from light sfermions on the lightest Higgs bosonproduction and decay at the Large Hadron Collider (LHC) within the MinimalSupersymmetric Standard Model (MSSM). We find that the scenario with lightcoloured sfermions -- stops or sbottoms -- has the potential to explain anon-universal alteration, as hinted by LHC data, of the gluon-gluon Fusion($\mu_{ggF}$) with respect to the Vector Boson Fusion ($\mu_{VBF}$) event ratesand, in particular, can predict $\frac{\mu_{VBF}}{\mu_{ggF}}>1$ for all Higgsboson decay channels in large areas of the parameter space.  We also find that the scenario with a light stop/sbottom can be complementedby the scenario in which the total Higgs width, $\Gamma_{\rm tot}$, is reduceddue to a suppressed Yukawa coupling $Y_b$. In this case, the reduction of theHiggs production rates in the $ggF$ process which occurs in the maximal mixingscenario is compensated by the reduction of the $H\to b\bar{b}$ partial decaywidth, the largest component of $\Gamma_{\rm tot}$.  Furthermore, we highlight the fact that, in the light stop/sbottom scenario,event rates with the Higgs boson decaying to a $b\bar{b}$ final state arepredicted to be essentially below unity. Therefore, during the future LHC runs,the measurement of $h\to b\bar{b}$ final states is a matter of specialimportance.  Amongst all viable MSSM configurations that we study (including revisiting alight stau solution), we emphasise most the scenario with a light stop, as thelatter is also motivated by Dark Matter and Electro-Weak baryogenesis. We alsoperform fits of the MSSM against the LHC data, emphasising the fact that inmost cases these are better than for the SM.
