  We study the effects from light sfermions on the lightest Higgs boson
production and decay at the Large Hadron Collider (LHC) within the Minimal
Supersymmetric Standard Model (MSSM). We find that the scenario with light
coloured sfermions -- stops or sbottoms -- has the potential to explain a
non-universal alteration, as hinted by LHC data, of the gluon-gluon Fusion
($\mu_{ggF}$) with respect to the Vector Boson Fusion ($\mu_{VBF}$) event rates
and, in particular, can predict $\frac{\mu_{VBF}}{\mu_{ggF}}>1$ for all Higgs
boson decay channels in large areas of the parameter space.
  We also find that the scenario with a light stop/sbottom can be complemented
by the scenario in which the total Higgs width, $\Gamma_{\rm tot}$, is reduced
due to a suppressed Yukawa coupling $Y_b$. In this case, the reduction of the
Higgs production rates in the $ggF$ process which occurs in the maximal mixing
scenario is compensated by the reduction of the $H\to b\bar{b}$ partial decay
width, 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 are
predicted 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 special
importance.
  Amongst all viable MSSM configurations that we study (including revisiting a
light stau solution), we emphasise most the scenario with a light stop, as the
latter is also motivated by Dark Matter and Electro-Weak baryogenesis. We also
perform fits of the MSSM against the LHC data, emphasising the fact that in
most cases these are better than for the SM.
