And the England keeper was certainly out to prove a point as he moved the ball quickly every time it came into his area.
It was just as well there was something to occupy Hart because, with a 5-0 cushion from the first leg, he was not going to be troubled and forced into action with his hands.
In fact, the second leg tie was such a waste of time that not only did Guardiola make eight changes from the weekend win at Stoke but Steaua even made six because they knew there was no hope.
It was no surprise that Hart’s grand total of action in the opening 45 minutes was nine touches with his boots and two with his gloves – neither a save.
It was more a question of whether City could add to their five-goal lead and, with Kelechi Iheanacho handed his first start under Guardiola, the teenager was another Blues ace out to show his worth.
After eight minutes, his long shot was City’s first goal attempt but was easily held by Valentin Cojocaru.
