what would you do?
most managers cannot afford to lose the players' dressing room
cause one lost, it means you are gone. Do you dare to put/use a
rotten apple?
Similiar with Cole, once found that his loyalty is with Chelsea,
sell him, why use it anymore?
and with MUFC, similiar with Rooney.
So what if the defence suffer a while, you gain the players', fans
and most importantly the management's respect that you dare to
act.
Imagine, in your office, someone who is very negative, and keep
smearing the management but he is the top earner, what do you
do?
by keeping him, you are affecting your own foothold as manager and
you lose control. by terminating him, you gain respect.
