West Ham boss Manuel Pellegrini has stated that Jurgen Klopp is "used to winning with offside goals" after Liverpool were held to a 1-1 draw at the London Stadium.
James Milner, who provided the assist for Sadio Mane's opener, was in an offside position but the assistant referee did not raise his flag.
Michail Antonio struck the equaliser shortly afterwards as he connected with a well-worked free-kick from the home side.
In the final seconds of the game, Liverpool striker Divock Origi should also have been flagged offside when he missed a chance to wrap up the three points.
Speaking after the game, Pellegrini stated: "Klopp is used to winning with offside goals.
"He beat me against Malaga with a goal seven metres offside - so he cannot complain about anything.
"They (Liverpool) scored a goal one metre offside. And in the last minute with Origi in front of the linesman, again one metre offside."
The former Manchester City boss added: "I said in the week that we need to win this game for our fans and if we are going to give a hand to Manchester City, well, they are my club also.
"Maybe that was the reason the manager of Liverpool didn't like it."
As the West Ham boss mentioned, the two managers met previously when Klopp's Borussia Dortmund beat Pellegrini's Malaga 3-2 in the 2013 Champions League quarter-finals.
Dortmund won the game thanks to two goals in injury-time and for the winner, four Dortmund players were in an offside position.
