Fallout from a fight?The big news coming out of the Arsenal camp this week was surrounding an apparent clash between Dani Ceballos and David Luiz.Many observers no doubt hoped to see the duo take to the pitch together on Sunday, with fingers crossed for some ‘afters’, but there was to be none – Luiz missed the fixture following the birth of his child this week.Ceballos brings the biteWhile fight fans will have been disappointed by Luiz’s absence and the lack of any potential for the Brazilian and Ceballos to come to blows (a stretch anyway, admittedly), the Spanish midfielder was often at the centre of the action at Elland Road.Following Lucas Torreira’s loan move to Atletico Madrid this summer, a certain bite in the middle of the pitch has needed to come from elsewhere.And Ceballos, more known for his creativity, has offered a degree of tenacity at times. It was on display on Sunday – and needed to be – with the Spaniard eagerly making a nuisance of himself as Arsenal chased the hosts somewhat.

In fact, that was the story for the majority of the match.Leeds failed to capitalise on their superiority – and their one-man advantage in the second half – but their showing was another sign of the promoted outfit’s capabilities at this level.Aubameyang puzzle persistsBefore kick-off, Arteta reinforced his opinion that Pierre-Emerick Aubemeyang is best-positioned out on the left.Yet, with wingers Nicolas Pepe and Willian lining up alongside him in a front three, the Gunners’ captain was deployed in the centre from the start, something Arteta opted to do for the first time in the Premier League.Having failed to score from open play in over two months, Aubameyang perhaps needed that opportunity in the endeavour to rediscover his best form for the club. But the Gabon international saw little of the ball, getting just four touches in the final third in the first half.Playing Aubameyang in the right position is half the puzzle, but Arsenal were fumbling with the pieces in failing to get the ball to their star man.Pepe’s moment of madnessPepe saw red – in both senses – when he headbutted Ezgjan Alioski in the second half, bringing his evening to an abrupt, early end.The Arsenal winger was seemingly reacting to some provocation from the Leeds man, but in thrusting his head straight at the Macedonian’s, Pepe presented referee Anthony Taylor with the easiest decision he’ll have to make all season.In a season in which Arsenal have struggled for consistency, they could do with every man pulling his weight in order to break out of this middling spell. Pepe failed in that regard on Sunday.This weekend get a £10 free bet with Betfair, when you bet £10 on a Same Game Multi on the Premier League.
