Massa must leave and kubica must replace him.
Honestly massa is not in the same class as alonso and he is being trounced by alonso.
First choice wouldn't be Kubica, but can understand why. He'd be easy to "buy" and IS a good driver.
I think Massa is either going to be judged on these last few performances or be threatened with replacement. I think Sutil is perhaps a guy to watch.... or who knows.... maybe even Schumi
