Leganes, who are now 10 points clear of the bottom three, led through Jonathan Silva at the Butarque Municipal Stadium before Benzema hauled Zinedine Zidane's misfiring side level early in the second half.
Leganes, 11th in the table, went close to winning the game but Youssef En-Nesyri had a goal correctly disallowed for offside. "He is a fantastic player and this year what has changed is that he has scored many more goals, so I am happy for him". Every player is good and important.
Most of Zidane's press conferences have so far been dominated by questions about his players' futures and on this evidence, few will be feeling secure.
His exceptional form has made him a target for the Beranbeu outfit but Florentino Perez would have to fork out over £130million if Mane were to leave the Merseyside club at the end of the season. "We make the changes to win the game, and we did not do that today".
