Part of the reason why Massa was flying at the end was because he 3-stopped. If you take into account the shorter stints, his pace wasn't amazing.
See how Bottas is just as fast, after getting by Kimi on lap 40, as Massa on much newer tyres.
to be honest massa was probably eithir de motivated or running on a lower engine mode knowing that there was nothing to gain or lose . how did williams not see that massa was losing 2 sec a lap in 1st stint did they actualy check the floor at the 1st pitstop i find it crazy that he had to do an extra stint going 2 sec a lap slower than he needed to.
bottas did a consistant job again although i thought the car should have beat red bull. if williams dont get 3rd and 4th at monza then that will be a massive disapointment
