Turkish champion Beşiktaş beat last season's Bundesliga runner-ups RB Leipzig in their second group-stage game of the 2017-18 UEFA Champions League on Tuesday.
The Black Eagles' attacking midfielder Ryan Babel put his team ahead 1-0 with a perfectly executed left-footed finish after Cenk Tosun's pass in the 11th minute.
The score remained unchanged until the 43rd minute when Anderson Talisca doubled Beşiktaş's lead against the German side after heading the ball home with a beautiful cross from Portuguese international Ricardo Quaresma.
Both teams failed to find the net after half time despite an abundance of goal-scoring opportunities.
The 2-0 win at Vodafone Park was the first victory ever against a German opposition for Beşiktaş after seven failed attempts in the previous seasons.
Having kicked off their campaign with a 3-1 win at Porto, the Istanbul giants now lead Group G with six points, while their closest pursuer Porto has three points. Monaco and RB Leipzig have one point each and occupy the last two spots in the group standings.
Beşiktaş will play their next Champions League match away against Monaco on October 17.
