Inter had a nervy last few minutes against Porto earlier this week, as the Nerazzurri had to hold onto their slender one-goal advantage right until the very end to see out the tie.
In stoppage time, the Portuguese side really ramped up the pressure as they knew that it was then or never for them to find a goal to force extra time.
Porto may well have found the back of the net were it not for an excellent save by Inter goalkeeper Andre Onana, which the Nerazzurri shared in a post on their official Instagram account.
