“We have to take a chance and play to win. It doesn’t mater if we lose, we have to try to win.” That is what Pep Guardiola told his team at half time. You have to play to win.
If you don’t focus on the top line, to score as many goals, chances of winning the match, however solid your defense is wont be possible. That is why most of the time the effort at cost cutting fails flat because chances of losing both ends is high.
