Sporting coach Ruben Amorim pledged to play his strongest team possible at the Etihad next month in a bruising post-match inquest.
What should have been a happy night for Sporting as they celebrated being in the Champions League knockout rounds for just the second time in their history quickly became a horror show when Manchester City scored four first-half goals to effectively eliminate their opponents with three-quarters of the tie still to play.
Pep Guardiola was f ar from happy with his City side but they managed to add another goal in the second half when Raheem Sterling curled home a beauty from outside the box, shovelling extra salt into the open wounds of Sporting.
