This is a rather disingenuous way of looking at it. One could argue what is lucky about Sturridge's stunning goal? It was a brilliant bit of football. Liverpool missed about 3 sitters that game, so it could also be argued that it would have been unlucky to lose, only for Sturridge's timely goal to earn a deserved draw.
Nothing lucky about Mahrez missing a penalty, imo. Alisson had it covered anyway, as he dived the correct way. Homework was done and once again, one could argue that if Liverpool lost that game, it would be unlucky, as overall it was a pretty drab affair where a draw was likely the deserved result for both teams.
Only the Everton goal was genuine luck, imo. That was surreal.
