  We analyze the constraints on coloured scalar bosons imposed by the current
LHC data at $\sqrt{s}=13$ TeV. Specifically, we consider an additional
electroweak doublet of colour-octet scalars, satisfying the principle of
Minimal Flavour Violation in order to fulfill the stringent experimental limits
on flavour-changing neutral currents. We demonstrate that coloured scalars with
masses below 800 GeV are already excluded, provided they are not fermiophobic.
