86' Ludogorets threaten again but Mustafi stands strong and defends well.
Lucas gets the ball on the left wing and immediately finds Ozil on the other side. The German's first touch finish is one directed towards the ground to ensure he gets an awkward bounce and it works. Arsenal are 5-0 up against the Bulgarians.
83' GGGGGGGGGOOOOOOOOOOOOOOAAAAAAAAALLLLLLL! Mesut Ozil again!
81' Ozil tries to release Lucas on the break but the weight of the ball carries it just too far out for the Spaniard to catch up.

78' Ludogorets applying the squeeze on Arsenal now who have failed to touch the ball in the last two minutes.

68' CHANCE! Alexis finds Ox with a lovely lob in the box but the Englishman's effort on goal is blocked well by the keeper. Corner to Arsenal.
67' Alexis is through on goal but Palomino brushes him off the ball. Ref waives away appeals for a penalty.

63' Ludogorets pull off some incredible moves when on the ball but fail to convert plenty of their chances.
62' Substitution: Lucas Perez coming on for Arsenal to replace the excellent Theo Walcott.
59' Meanwhile, Santi Cazorla is having his leg iced on the bench. Looks like an injury forced him off.
58' CHANCE! Theo puts in another cross but the keeper collects well.
57' Substitution: Elneny comes on to replace a visibly disappointed Cazorla for Arsenal.

42' GGGGGOOOOOOOAAAAAALLLLLL! Theo Walcott again for the Arsenal!
40' Arsenal break through the Ox but he can't find Alexis or Bellerin and the Bulgarians clear. A lot of frustration on the pitch at the moment - especially from the home side.
