The Senegal international scored his 18th and 19th goals of the season in the 3-1 win over Bayern Munich which put the Reds into the quarter-finals of the Champions League.
"He is really good. The games tell you that, he is really important with his goals and assists. A good season, his best with us," Wijnaldum said.
"They (media) do not speak about him? I think the other players have shown they get the headlines but Sadio also.
"He has had a big influence on winning games. Mo did not score (against Bayern) but had a good game.
"People speak about the player who had two goals. A lot of players do the work and make the difference.
"You have to speak about everyone. For me, Sadio is up there with those players you named."
