Christian Benteke scored his first Premier League goal for Liverpool via a contentious strike, as the Reds beat Bournemouth 1-0 at Anfield.
The £32.5m signing was the difference, as he netted the game's only goal in the 26th minute of the match. However, the goal should have been called offside.
Brazilian Phillipe Coutinho was clearly offside before the ball was crossed in. Coutinho attempted to get his foot on the Henderson cross before it reached Benteke. Under last season's guidelines the goal would be legal, as Coutinho did not play the ball.
However, under the new guidelines introduced for this season, the Liverpool No.10 was offside, having made a clear attempt to play the ball in front of goalkeeper Artur Boruc.
What made the decision worse was that Bournemouth had a goal of their own disallowed in just fifth minute when Tommy Elphick headed home from a corner. The referee ruled that Elphick pushed Liverpool backman Dejan Lovren to reach for the header. However, it too was a contentious decision, with the contact appearing minimal.
The goal seemed to kick Bournemouth into gear as the visiting side had most of the game's clear cut chances in the second half.
But Benteke had a chance to double the lead just a few minutes from time, but his shot hit the crossbar from close range.
Captain Jordan Henderson was substituted in the 52nd minute of the match, with coach Brendan Rogers later revealing his skipper is battling a foot injury and may be in doubt for next week's match against Arsenal.
Liverpool now sit in third spot after two rounds two 1-0 wins from two games.
