The Reds were awarded a spot-kick when Jerome Thomas was adjudged to have fouled the Uruguayan after only eight minutes.
Asked for his verdict on Suarez's performance, Scharner said: "It was a nice dive for the penalty and that got Liverpool well started for the game.
"It put us under pressure and we weren't good enough to respond.
"He (Suarez) is very good at winning penalties. He's one of the best on the planet, in fact. I had a good view of it.
"If that's a penalty, then you will find 1,500 penalties are given in every match.
"I know it was the assistant who flagged for it and maybe he had a better view than the referee. But there was a general feeling amongst all the players that it was a soft penalty."
