Arsenal manager Arsene Wenger has expressed his surprise that his team are the first English club to progress to the next stage of the Champions League.
The Gunners booked their place in the last 16 with a 2-1 win against Borussia Dortmund at the Emirates Stadium on Wednesday night.
However, results for Manchester City, Manchester United and Chelsea on matchday five means that all three clubs need results from their final games to join Wenger's side in the next round.
When asked if he was surprised by the situation, the Frenchman said: "Yes - I have to be very cautious what I say.
"I think yes as Manchester United could have qualified [on Tuesday] night, and of course everyone expects Manchester City to qualify.
"The groups were very difficult for the Premier League teams. The level has gone up a lot and we were in a difficult group, so I am very happy and pleased to see where we have come from."
The Gunners next host Fulham in the Premier League on Saturday.
