1). Kimi xouldnt push too much. His front wing was damaged. No question of him not being motivated enough or whatever. Last year he had a disastrous race at Monaco. He is going to rule there this year. MAssa isnt very good at the tight circuits.

2). Massa let Hamilton pass because he couldnt keep him behind him. Simple. He knew Hamilton was on a 3 stop strategy and knew the race was in the bag. No point in fighting in too hard and crashing out
