fwiw, i think Benitez will continue to roatate and manage his squad for all three competitions, because he thinks that Chelsea have the squad depth that is capable of doing so. If this is his thinking, it will be good for our (and arsenal's) chase for top 4. But i think there is also a genuine argument for Benitez in rotating his team in this manner.
if chelsea had beaten southampton, no questions would have been asked regarding his team selection that day (i also think the likes of ferguson, wenger wouldve rotated in a similar manner). and a lot of the abuse Benitez has taken regarding his rotation/soton result has come from that fact that there are many bitter chelsea fans looking to have a go at him whenever possible.
