All sounds almost professional, except perhaps this bit - 'However, we are not currently a Champions League team, and in six seasons out of the last ten we have finished in the bottom half of the Premier League.'
That shouldn't be a detractor but a positive. We should have done better and with you at the helm we would have done - and now will if you come on board. Saying we can't get a top manager because we haven't achieved as much as we could have hardly seems apt somehow.
