While I am in no way condoning the action and feel there should be a solution that can accommodate Banzo and Tam in the team, if Caldwell has identified them as part of the problem, he has the right to make the changes he thinks necessary. However if this happens, he will live or die on the results and if they don't improve, he will be under extreme pressure.
That said, if we now win the next 5 in a row, will all those criticising him now be man enough to give credit for what must be a brave decision ? I hope I will.
