Patrick Vieira has questioned some of the officiating after his Crystal Palace side were beaten at Liverpool.
Goals from Sadio Mane, Mohamed Salah and Naby Keita sent the Eagles tumbling to a 3-0 Premier League reverse at Anfield on Saturday.
Palace fashioned a number of chances with the Reds indebted to a clutch of fine saves from goalkeeper Alisson Becker, with the visitors having first-half penalties claims when Wilfried Zaha and Christian Benteke tangled with Ibrahima Konate and Kostas Tsimikas respectively.
And Palace boss Vieira said: “I think 3-0 is quite difficult and severe considering the number of chances we created, the situation we created.
“We were really poor defending our set-pieces and you can't concede three goals on set-pieces at Anfield if you want to take something from the game.
“When you are coming to places like Anfield a lot of the decisions will go their way, that's the way it is. I don’t know if that's the way it should be.
“There were some situations where I believe those decisions should have gone our way but the frustration is about coming to a difficult place like this, wanting to take the result and then conceding three goals from set-pieces.
“It is difficult for us to hope of taking something from the game.
“I think as well we had a number of chances and our decision-making in the last 30 yards wasn't good enough to score those goals or to create those goals.”
Vieira added: “When you come to a difficult place like Anfield you need a little bit of luck as well and we didn't have it today.
“We created chances, we conceded chances as well, but when you come to a place like this with the players they have you expect to go through a difficult period and we had a difficult period but we showed a lot of solidarity and the key for us was we couldn't score that goal, especially in the first 15-20 minutes.”
