Jeglertz has successfully rotated his squad this season and did not hesitate to do it again even in the derby, leaving experienced vice-captain Kerstin Casparij on the bench for the first hour.
However, that experience was missing in the first half as City looked disjointed and frustrated, unable to make their dominance count.
The players trudged down the tunnel at half-time with Shaw visibly annoyed having failed to have a shot of any kind, or even a touch inside United's box.
The Jamaica striker was involved in several tussles with United captain Le Tissier, but it appeared the physicality of the match favoured the hosts.
Asked about the challenges on Shaw, Jeglertz said: "It is not becoming anything too unpolite. That's how it is in these games.
"She is very strong and sometimes she gets knocks and hits that takes a lot to make her fall to the ground. Sometimes I feel the level of what [the referees] give her is not right."
As the game went on, even after Shaw had broken the deadlock, City looked more unsettled despite Jeglertz turning to his bench to try to change it.
United put pressure on City and grew in confidence, eventually creating the opportunity to test their defence with a free-kick late on - and it was Shaw who was caught out in the box with a loose header.
City do not have time to dwell on their performance with matches coming up thick and fast in November, but they at least came away with a point despite a patchy display.
