Starting with a percolation model in in the subcritical regime, we consider a random walk described as follows: the probability of transition from to is proportional to some function of the size of the cluster of . This function is supposed to be increasing, so that the random walk is attracted by bigger clusters. For we prove that there is a phase transition in , i.e., the random walk is subdiffusive for large and is diffusive for small .
