If it wasn't for his hat trick then he definitely would have done. If we didn't have a 2 goal cushion in the 96th minute I think he would have done also. Sterling did similar when attempting to get his hat trick vs Arsenal (except he missed) so he can hardly complain.
Suarez has been laying it on a plate for Sterling this season and they have a good bond, I think it will continue and you can begrudge the man from wanting to use the last kick of the game to get a hat trick!
