A number of fans sent abusive messages to Duggan as she posted the photo just hours after City’s 4-2 defeat to Manchester United last weekend.
Duggan later removed the picture, which also contained City player Isobel Christiansen and Everton player Michelle Hinnigan, from her Instagram account.
Duggan apologised for the post and reiterated her commitment to City following the abuse.
Speaking on her official Facebook page, Duggan said: “I would like to apologise to all MCFC fans for the error of judgement I made last night.
“I now appreciate the significance of my actions and can assure everyone connected with Manchester City that I am proud to represent the Club and wear the shirt.”
For Duggan to apologise to grown men who attacked her for doing nothing wrong seems ridiculous.
The timing of the picture could have been a lot better but such a meeting between staff of two rivals is not without precedent. For instance, United’s Rafael joined Liverpool players such as Coutinho for Lucas Leiva’s birthday celebrations last year but nothing was made of it.
Unfortunately, the rise of social media has made it almost impossible for football players to simply enjoy their lives and this case of bullying and intimidation went way too far this time around.
