Despite City taking the lead in the game through John Stones, they had to settle for a point after Alexis Mac Allister scored Liverpool's equalizer, with Ederson going off soon after.
"Good moments from both sides. We started really well. We have to never ever forget when we play in this stadium otherwise we don't have a chance, knowing it will be so difficult," Guardiola told reporters post-game.
"It was a tight game on moments. Not a game where all the time a team controls it. A lot of credit to Liverpool. They proved again what they have done is unbelievable for this rivalry. I know how difficult it is to come here and win.
"The players gave everything. I give credit to the opponents and take the point. We knew we would have 10-15 minutes when it is a tsunami and you have to survive. We are there, we'd loved to have won but we could have lost. It is what it is."
On Ederson, he added to beIN Sports: It doesn't look good."
