Mesut Ozil has come under-fire in recent weeks for his poor performances in an Arsenal shirt.
The 28-year-old has failed to find the net in his last eight Premier League fixtures.
And Arsene Wenger admitted at the weekend after the 2-0 win over Hull that Ozil was low on confidence and has challenged him to return to scoring form.
But it was in the Champions League group stage earlier in the season that Ozil found his shooting boots, including a hat-trick in the 6-0 win over Ludogorets.

Wenger stopped short of revealing his team tactics for tomorrow night but hinted that Ozil is ready should he be included.
"It’s not the best moment to give out the XI," said Wenger in today's pre-match press conference.
"I will pick the team tomorrow.

A positive result tomorrow night in Germany could put Arsenal in the driving seat going into the second leg at the Emirates in three week's time.
Arsenal have not progressed from the last-16 since 2010 – twice being knocked out by Munich – but on both occasions the Bundesliga giants held the second leg home advantage.
But Wenger has reminded his side that having the home leg advantage will count for nothing if they fail to get a result in Munich tomorrow.
"It will be important. But on the condition we have a good performance tomorrow night," Wenger added.
This will be the fourth time Arsenal have met Bayern Munich in five years
"This is a massive challenge – but I think we are capable to deal with it."
Arsenal have tasted success in Munich before and have only lost once in their last three visits to the Allianz Arena.
And Laurent Koscielny is confident his side can repeat their recent success to give them the upper hand.
"We know we are capable of winning here, we've done it before," he said.
"The first game is very important, otherwise the second leg at home means nothing."
