Arsenal manager Arsene Wenger is confident that his side can beat Olympiakos and qualify for the Champions League knock-out phase following their 3-0 victory over Dinamo Zagreb, according to reports from the Mirror.

The Gunners kept their European Cup hopes alive with an impressive display at the Emirates, but they know they will need to beat the Greek champions on December 9 to get out of the group.

Alexis Sanchez was the star man of the night with two goals and an assist for Mesut Ozil, and after the performance Wenger revealed his side are now making up for their poor Champions League form earlier in the campaign.

He said: “At least tonight we have come out with a chance. Let's make right what we didn't do right until now.

“We wanted to come out of the game with a chance to qualify. We needed to do the job, and Bayern needed to beat Olympiakos. Both did it well and it gives us a chance. How big the chance is I don’t know but I believe we can do it.

“We just need to win. It might not be enough. But if you lead 1-0 they will be in the situation where they can lose it and we will be in a situation where we can win it.

“So we have to go there and win the game. If you can win 1-0 you can win 2-0 as well. For us the task has one advantage – it’s very clear.”

The Frenchman went on to hail Sanchez’s form, and admitted that he wanted to take the Chile international off ahead of this weekend’s Premier League clash against Norwich, but was unable to after already making three substitutions.

“He’s just a very important player,” added Wenger. “At the moment in real strikers we have just Giroud and Alexis. All these strikers are needed. Giroud had a little problem with his ankle over the weekend and I decided to give him a breather.

“Hector Bellerin came off because he had a groin problem. Then I couldn’t take Sanchez off. But now we have five days to recover.”

Sanchez, 26, has made 24 appearances in all competitions this season, scoring 15 goals.
