The boss confirmed that Mendy was also back in training on Friday and could play.
Asked about City's clashes with Liverpool last season Guardiola added: "Every game is completely different. In the first Champions League game we made a good performance except at the end of the first half.
"At home we made very good game as well. It doesn’t matter that we lost. Since Jurgen took over he has a lot of weapons to attack on the counter and in set pieces and they take advantage of mistakes.
"They are so good at making a real attack and the three guys in front connect very well. They are a top side and reached the Champions League final."
