A late howler from goalkeeper Stekelenburg robbed Magath of a debut win.
Magath, though, could not blame Stekelenburg for the equaliser, in particular as the 31-year-old otherwise pulled off a number of fine saves, with none better than in injury time to deny Chris Brunt the winner.
"He (Stekelenburg) played very well," said Magath.
"It was a shot from only a few metres and such things can happen. I don't see the keeper being at fault. I don't blame him."
Although undone by the introduction of new technology, Magath again had no qualms as he has long been an advocate.
"I wonder why everybody doesn't have such technology," added Magath.
"When everybody sees a ball is behind the line, it's terrible if the referee doesn't see it and makes the wrong decision.
"So I remain a fan. I always fought for technology in Germany."
