The presentation aimed to educate the young squads, from the U15s age group to U23s, on what happened on April 15, 1989 from a family perspective.
Margaret and Sue were then asked questions by the young players before being presented with flowers on behalf of the club by U18s striker Yan Dhanda.
Academy director Alex Inglethorpe said: “It was an absolute honour and privilege to welcome Margaret and Sue down to educate the boys on what happened at Hillsborough.
“It was such a poignant and emotional speech, which I’m sure will give the players an insight into the real fight for justice that the families had for 27 years.”
Aspinall added: “It was great to meet the young players at the Academy and speak to them about what happened in 1989 and know the real truth over what happened post the disaster.
“The lads were very respectful, and Sue and I would like to thank them for inviting us to speak to them.”
