Arsenal reached the knockout stage of the Champions League for the 15th straight season with a 2-0 win over Borussia Dortmund on Wednesday night, and Liverpool put itself in position to advance if it wins at home over Basel next month.

“I’m very proud of that and the club deserves a lot of credit for that,” Arsenal manager Arsene Wenger said of the streak.

“It’s not enough because we want more than that, but we are consistent.”

Atletico Madrid and Bayer Leverkusen also clinched berths in the final 16.

Liverpool and Ludogorets are 1-3-1 with four points, and Liverpool holds the tiebreaker based on head-to-head record going into the Dec. 9 match.

“We need to win a game at the end against Basel, and at the start we would have looked at that game as the one to see us through,” Liverpool manager Brendan Rogers said. “It should be a great night at Anfield.”
