If Rafa departed after this season, I find 2 identical situation.
Houllier departed after brought Liverpool to second place in league with 80+ points but still finish second (which in ordinary sense should be good enough to be champion)
Rafa managed to bring Liverpool to second with 80+ points as well but still finish second even with 2 losses for the whole season, (which in ordinary season, can be champion as well)
Liverpool best fengshui is second only??
A good team shouldn't be with out 2 players then the whole team disjointed can't play well. Yes, losing start player will result some weakness, but not the like whole team cannot perform at all. It is not like missed chances lead to no goal, but there is little chance created throughout the match.
Somemore Liverpool has one of the worst defence in away matches, never have clean sheet if not mistaken, the most on the top 10 except Burnley and if Burnley win the unplay match, Burnley same point with Liverpool after Quarter of the season passed.
