Guardiola was also critical of his players, as he added: "It can be fragile because it happens so many times. But we have a duty to learn and there are always margins to get better. It’s happened all season, we are giving away too many things, we are aware this cannot happen, but it happened.
"It is hard to put into words straight after a game like that. Pride hurts. Sorry to the fans that have travelled to come and watch that. How we played in the last 30 minutes was not acceptable. Personally and collectively, it’s not us.
"It is not nice to be involved in that when you know it’s not your team in those situations. We were in the game and it was a swinging point. It swung the wrong way for us. I am angry, upset personally and collectively about how the game finished. There are a lot of different things that I still haven’t figured out as to why it hasn’t clicked. The heart’s there, the passion’s there; everyone’s got the right intention. We all need to stick together."
