#1 Rudiger at fault but cannot be blamed
Antonio Rudiger was responsible for both the Arsenal goals but he cannot be blamed for it. Both were unfortunate incidents and it's something that happens to all the players.
For the first goal, Rudiger was looking for the Arsenal players in the six-yard box when the bizarre goal went in. The ball, headed by Nacho Monreal was going straight towards Willy Caballero. But unfortunately, it hit Marcos Alonso's head and then hit Rudiger's and bobbled in.
For the second goal. Rudiger made an honest attempt to block Lacazette's cross but was unlucky to see the ball deflect off the inside of his leg and fall right in front of Granit Xhaka. The Swiss international made the most of the opportunity and slotted it home to win the game for Arsenal.
