Only Manchester United have managed to deny Jurgen Klopp's side three points in the Premier League this season following a 1-1 draw with Liverpool FC at Old Trafford last month.
Guardiola said Ederson was an injury doubt for City's trip to Anfield on Sunday after hobbling off during the Champions League draw with Atalanta.
Sadio Mane scored a late victor for the Reds in Saturday's 2-1 Premier League win at Aston Villa but was earlier shown a yellow card for simulation, having previously been criticised after winning a contentious late spot-kick against Leicester City. "Oh they were good and we had to defend with all we had but we scored incredible goals".
Klopp also admitted he would prefer to take back his comment on tactical fouls, saying: "I then said what I said but come on, I can't let it go completely without a comment!"
"I am so proud of my team, more than ever".
"So probably right now they are the strongest team in the world". But I am really not interested.
Sunday's result could prove to be massive in the title race this season, and Klopp was not surprised when Man City dominated the game at Anfield, but Liverpool's intensity helped to see them over the line.
But the Reds are facing a daunting run of games, playing every few days from after the worldwide break until the new year, and Klopp says every Premier League point amassed so far will be needed to help them through that period. I don't really care - we want to win.
Former Manchester United striker Berbatov is backing Manchester City to beat Liverpool FC at Anfield on Sunday afternoon.
"When you see the statistics, I don't believe much in these sorts of things, but 38 years for one (win), it shows how hard it is at Anfield". And then we will see what the situation is. "Definitely. We know it", he said.
'If he would not play it would change the game because Ederson is an important part of the game. "Maybe other teams can do it a different way but this is the only way we can beat them". I'm pretty sure that if there's a chance to win at Anfield it's when you believe you're going to win the game.
