They have to have a second driver who's shite because the Alonso has a pink fit if there's focus on anyone other than him.
They also need another driver who is capable of reliably winning constructors points if they are to ever have a hope of winning that title, don't forget that in reality the team only gets kudos from one of their drivers winning the drivers championship. No matter what Alonso does to bring in sponsors Massa's recent bumbling is likely to alienate more than a few companies who are willing to splash the cash, then you end up in a situation where wholly inappropriate sponsors like Chelski are the only ones left.
