Manchester City boss Pep Guardiola insists all their past success counts for little today against Liverpool.
At City, Guardiola has earned four Premier League titles, four League Cups and an FA Cup.
He said: The past is the past, experience doesn't count.
I hear sometimes players or managers say 'I don't have to show anything or demonstrate anything because of what I have done in the past'. It's the most awful sentence.
You have to prove it every single day, again and again and again. The past is the past.
For the memories when you are a grandfather it's nice but the reality, the people tomorrow will come to the Etihad Stadium and they won't think about what we have done in the past.
You have to [do it] again and again. Otherwise you have to retire.
I never play a game thinking because of my experience in the past I am going to win this game.
I think in football, what you have done yesterday doesn't count for tomorrow."
Guardiola added: I never think [that you should] overestimate me so much or the team so much that this is not going to happen.
Every time, it can happen what happened to Liverpool this season or with other cases. It can happen to us absolutely.
When it's going to happen, [you have to] try to find a solution as soon as possible to avoid it.
[If] it happened two bad weeks, three weeks, [on] the fourth week try to find a solution to avoid it.
And when that happens, accept the storm and always tomorrow the sun will rise.
The only thing I believe is don't complain and find a solution and try to avoid it. But know that can happen!"
