The result leaves Juve in fifth place, seven points behind leaders AC Milan.
But Pirlo says, “Our ambitions remain the same. It's a slip-up against a strong opponent, these things happen, but what I am disappointed by is the attitude. A side like Juventus must come here with a certain confidence and ambition, the desire to take the initiative and steer the game in a certain direction, but we were too timid.
“We were too slow in our passing and above all did it with our defenders rather than the midfielders. We wanted to create the situation where Chiesa could take men on or Ramsey could go between the lines. That didn't happen, because we moved it too slowly and too deep, so we never really pulled Inter players out of position. We were too predictable.
“The coach is always the first to take the blame, as if the team didn't do what we planned, it means we didn't understand the plan.
“We were disorganised on the opening goal, didn't follow their through runs and were caught out. It all became more difficult from there."
