David Luiz scored his first goal for Arsenal as Unai Emery's side beat Bournemouth 1-0 at the Emirates Stadium.
The Brazilian defender, who completed a move from Chelsea in the summer, headed in from a Nicolas Pepe corner in the first half and the goal was enough for all three points against the Cherries.
Speaking after the game, Unai Emery praised Luiz: "The most important is to have a lot of corners. We had a lot in the first half.
“When we have a lot we can score. He is very positive. He is every time speaking about positive things. He is helping the young players.
“He came late in the squad but his commitment is very high, his behaviour.”
After scoring the match winning goal, Luiz was understandably delighted, but one of his teammates also showed remarkable enthusiasm in the celebration.
New club captain Granit Xhaka could be seen sprinting after Luiz and then jumping onto his back before bringing him down, which sparked a giant pile-on from the other Arsenal players.
And Arsenal fans took to social media to laugh at the rather vigorous celebration from the Swiss midfielder.
