Denmark striker Yussuf Poulsen created the opening goal and then added a brilliant second with an acrobatic bicycle kick as his side beat Serbia 2-0 in their Nations League A Group 4 clash on Sunday. With group rivals Switzerland and Spain set to meet later on Sunday, Denmark tops the group with a perfect six points from their opening two games. After an industrious display in his debut on Thursday when Denmark beat Switzerland, attacking midfielder Albert Gronbaeck gave his side the lead against Serbia with his first senior international goal in the 36th minute, playing a one-two with Poulsen before drilling the ball into the net.
