My retort to this would be "and bring in who?!".
It is an art form which has been neglected over the years, with the introduction of Adam Gilchrist. Very few are going to have that ability with Bat and Glove again - Dhoni being the obvious comparison.
Who in England is good enough with bat, or gloves, to replace Matt? I would argue, currently, noone.
Buttler and Kieswetter are the two obvious candidates for me - however, they need ALOT of work done on their techniques - this will take time. They cannot be thrown into test cricket and be expected to operate at the level Matt has been working at for the past few years.
It is obvious that Matt needs a break, but I don't think dropping him for good is a viable option with the people we have in reserve.
