Riding luck is not good enough

We lost 2-0. We rode our luck to fullest, but they decided to take the matter straight forward by being physical. We rode the luck for 72 minutes, but we weren't physically up to the challenge by putting the body on them.
When they forced the issue, we allowed them to do whatever. We had lots of scare, but there is so much you can do, when you get physically tired, by getting the blows.
Running around to chase the ball and when we did win back the ball, we couldn't posses for more than 3, 4 passes.
We deserved the loss.
