I thought A-Rod played quite well last game, especially considering he hasn't had consistent game time. I thought he made a few stray passes, though, that could've cost goals (remember one bad backpass which resulted in a Siggy Spray)
I do think he has far more potential to become better than Lia does if he gets consistent game time, and at the moment I'd put A-Rod above Lia most of the time.
I don't think Lia is the cause of all ills, but I do think he's not good enough to be starting for us most games.
