delay in introducing VAR came under the spotlight Saturday when Manchester City dropped early points in its title defence in a 1-1 draw at newcomer Wolverhampton.
The hosts then took the lead in the 57th minute as Boly turned in Joao Moutinho's cross at the far post with his right hand, with City then denied a penalty despite David Silva appearing to be pushed over in the box.
City responded thanks to Aymeric Laporte's first goal for the club, but were left to rue their luck as the visitors hit the woodwork three times through Sergio Aguero and Raheem Sterling.
Both sides had opportunities to win it in the closing stages, with City nearly snatching three points when Aguero's free-kick glanced off the bar with virtually the last kick of the game.
The Premier League's defending champions Manchester City are off to the their title's defence in the flawless manner. Mo Salah netted his second of the season for The Reds, but more interestingly his 29th goal in 29 league games.
Salah, the league's top scorer previous year, scored the first-half victor on Saturday to give Liverpool nine points from three matches after Manchester City's spotless start to their title defence was halted by a 1-1 draw at newcomers Wolverhampton Wanderers. It's the most City have been exposed since the Liverpool away game in January.
"They (the players) knew it would be a tough challenge but we just go for it and played".
City were good value for their point but they looked unusually vulnerable against Nuno Espirito Santo's well-drilled side.
"Unfortunately the referee was probably the worst performer today, and that's why we lost two points", said Gundogan as quoted by the MEN.
"In the past two weeks in training I've seen the Leroy that I know and we know".
"But, of course, the spectators in the stadium and the audience on TV enjoyed [Wolves against City] because they had chances, we had chances".
Only three games into the season, Rui Patricio has staked a pretty good claim to save of the season.
While City had much the better chances, Wolves were ambitious in their approach and offered a threat throughout.
