Magath, whose team have floundered in the Bundesliga after being runners-up last term, has been under mounting pressure following a string of underperforming winter signings and his 10th-placed team's poor start to the year.
Even the club's bosses have been publicly questioning his wide-ranging powers at Schalke in a disappointing season that was preceded by another line of big name transfers that have largely failed to pay off.
Just days before Raul's 64th minute equaliser in a 1-1 draw in their last 16, first leg tie that gave Magath a much-needed boost, the coach was asking for the fans' support through his newly-established Facebook page and a four-minute video.
"We have now a very good starting position for the return leg (on March 9) but we are aware that there is a huge task still in front of us," Magath told reporters. "Raul proved again today that he has lost none of his class as a player."
"We will face a team with a high level of intensity in the second leg and we will be prepared for exactly that. We will need to play our best game if we want to advance," said Magath.
