This was a bigger battle than many Manchester City and Premier League fans had been expecting, as Rodri scraped the win by curling a right-foot finish through a gap between players with 15 minutes to go.
Nonetheless, the Nerazzurri had more than a few chances to equalise, Federico Dimarco hitting the crossbar – and Romelu Lukaku – before Lukaku’s header was straight at Ederson.
“Unbelievable. Difficult to put in words. Today we made history,” captain Gundogan told BT Sport.
“It was difficult for both teams. We weren’t at our best in the first half. We were hesitating. We knew we had to do better in the second.
“It was probably a 50-50 game. We feel very fortunate it was for us.”
However, Gundogan denies that the pressure of being the over-riding favourites got to Manchester City this evening.
“We knew everyone was talking about the Treble. The pressure was there, but this team is built to handle the pressure in the best possible way.”
