Liverpool manager Jurgen Klopp commented on Manchester United's defensive tactics following the 1-1 draw at Old Trafford.
The German manager also protested the decision to allow Marcus Rashford's opening goal, questioning the VAR's decision not to give a foul for Victor Lindelof's challenge on Divock Origi.
Despite Liverpool managing to get a late equaliser through, substitute Adam Lallana Klopp was critical of what he perceived to United's defensive tactics.
"When we come here this year, last year and the year before they just defend. It's not criticism, it's just a fact," said Klopp.
"The quality they have, (when they) set up like that, it's really difficult. It's no excuse, we needed to do better."
There was more frustration for Liverpool as Sadio Mane had a goal ruled out by VAR following a handball.
The Reds fought back in the second half and levelled the score when Lallana slotted in at the back-post as the game ended 1-1.
The result ends Liverpool winning start to the league this season, but they remain top of the Premier League, six points clear of defending champions Manchester City.
Manchester United, on the other hand, are 12th in the table with just ten points from their first nine league games.
Liverpool will play at home to Tottenham in their next Premier League game while Manchester United will play away at newly-promoted Norwich.
