So we want Birmingham to beat Trent tomorrow. Then Manchester to beat Trent on Sunday. That would ensure that Trent join Manchester in finishing below us. 4th would be the lowest we could finish.
And then, depending on what we do on Monday, we would either want Superchargers to Birmingham (if we win) on Tuesday, or Birmingham to beat Superchargers (if we lose). The latter would see Birmingham win the group, with us and Oval going into the eliminator. The former would see us win the group, with Birmingham and either Oval or Superchargers go into the eliminator.
Obviously if we win on Monday, we'll be through regardless of what happens tomorrow and Sunday. But it would be nice to keep that second chance available to us, just in case we were to slip up (whilst also keeping alive our chances of winning the group if we were to win).
