The Sky Blues mustered 17 corners and 21 attempts on goal compared to the Blades' six and four, statistics which served to highlight the one-sided nature of the npower Championship encounter and the heroics of Simonsen.
The former Stoke stopper denied City time and time again while Gary McSheffrey could only watch in agony as two second-half free-kicks came back off the crossbar before he fired over a golden opportunity in injury-time.
It added up essentially to two dropped points for Aidy Boothroyd's out-of-form promotion chasers, who are now without a win in seven league games.
But his United counterpart, Micky Adams, a former Coventry player and manager, was able to welcome a valuable point in the struggling club's bid to avoid the drop.
