Arsenal captain Per Mertesacker has insisted that the club are still capable of qualifying for the round of 16 of the Champions League.
The Gunners lost 5-1 to Bayern Munich on Wednesday night and are bottom of their group with just three points from four matches, six points off second place with just two matches left in the group stages.
“They scored too early for us and got into their rhythm – that was too difficult for us to go again,” Mertesacker told BT Sport moments after the Munich massacre.
“It was disappointing from our point of view but because they scored early, they got into their rhythm.
“We have to win both games and get two goals on Olympiakos, but it’s not over and that’s how we have to approach it. We need to bounce back and put away negative energy.”
Arsenal will still qualify if they beat both Olympiacos away and Dinamo Zagreb at home, while the Greeks fail to gain any points in their final two , matches.
