Referencing Skrtel's performance in the 4-1 win against West Ham United on Saturday, Mignolet said: "Martin was so unfortunate with the own goal. But all the clearances he made before that and all the headers he won more than made up for that.
"He has been so good for us week in, week out. He has been in top form since the opening few weeks of the season.
"He was unlucky not to get on the score-sheet at the other end as it was given to Mamadou Sakho instead."
The Reds are currently second in the Premier League.
