City come into the tie hoping to extend our winning sequence in the Premier League to an incredible 12 matches.
Victory in Saturday’s lunchtime kick-off would also see us extend our lead at the top of the table to 13 points for at least 24 hours.
And Guardiola insists that looking towards the next game rather than dwelling on our achievements so far this season has been crucial to that success.
“Football is (about) constant evolution. You have periods where you play good, but the key is to sustain that for as long as possible, this is what you have to do,” the City boss declared.
“Tomorrow, the test we have ahead of us is to face the European champions.
“(They are) an excellent team in all departments and the way they play with personality.
“It’s another test and another game to try and win, make three more points and come back in our best way.”
