Quite a sizeable one as well. If we take out the home field advantage (which accounts for roughly 0.35 goals), the market rates Liverpool the better side by about 0.5 goals which is huge considering they are behind United in the table. Now I've been saying for a long time that United are worse than their league position suggests and have been betting against them on the handicap lines but even I'm surprised by that. I was big on Spurs some weeks ago when they beat United and were priced at ~2.40 to win. This suggests that United were rated the better side by about 0.2 goals (again eliminating HFA). Put those two games together and we arrive at Liverpool being a 0.7 goals better team than Spurs. This is nonsense obviously and the odds in the Spurs were just wrong but it is still a remarkable market shift. Almost tempted to bet something on United today.
The line was surprising especially how we played against Chelsea, however when the line moves like this it indicates all the "smart" money is on Liverpool and it's going to be a losing play betting against them long term so I'm just going to stick to just watching.
