"Manchester City" strategist Pep Guardiola insists that it is necessary for his players to win the return match against "Barcelona".
According to the Spaniard, the "citizens" will have to fight as if it were a final.
The points are really needed for the English club, as after three games they have only earned four points, and a loss today could push them to third place in Group C.
"I think we know what we need to do to win. They know us, but I hope our attacking potential will be significant," Guardiola said at a press conference.
"We have to play like it's a final. It's not a final for them, but it will be a final for us. There are only three games left. We lost two points against Glasgow against "Celtic". So, we will try again," he added.
"I have never thought that we cannot win, I have never stepped onto the field with such thoughts. To win, we must play almost perfectly, but if we fail, we will congratulate them and start thinking about the matches against "Celtic" and "Monchengladbach", which will take place in the next few weeks."
