Can f(R) gravity isotropise a pre-bounce contracting universe?

We address the important issue of isotropisation a pre-bounce contracting phase in $f(R)$ gravity, which would be relevant to construct any viable nonsingular bouncing scenario gravity. The main motivation behind this work is investigate whether by itself, can isotropise universe starting initially with small anisotropy without incorporating super-stiff or non-ideal fluid, that impossible general relativity. Considering Bianchi I cosmology and employing dynamical system analysis, we see not possible for $R^n$ ($n>1$) $R+\alpha R^2$ ($\alpha>0$) theory, but $\frac{1}{\alpha}e^{\alpha R}$ theory. On other hand, if one does specify an theory priori demands smoothly connecting ekpyrotic contraction bounce, \emph{may} fulfil condition physically viability simultaneously.
