|7/4||Fulham are 7/4 with Betway to beat Newcastle on March 15|
Steven Caulker scored twice for Ole Gunnar Solskjaer’s charges, either side of Lewis Holtby's equaliser, before Sascha Riether's own goal put the seal on a miserable day for the Cottagers, who are four points behind 17th-placed West Brom.
Mitroglou, who played an hour in a friendly for Greece on Wednesday, made his first start since his £12 million move from Olympiakos in January but failed to impress against Cardiff and appeared short of match fitness.
"He [Mitroglou] is not used to a relegation fight," said Magath.
"He came from the best club in Greece and the best club was better than the others in the league.
"He's only used to scoring and that's his strength. Here in the Premier League it's the best league in the world so he needs to get used to it.
"He's not used to it. Unfortunately he had some opportunities but at the moment he's not in the situation to score."
