Arsenal went past opponents West Ham and climbed into fourth place in the Premier League with hard fought win in an eventful match at Emirates Stadium.
Gabriel Martinelli slotted away the opener shortly into the second half before late substitute Emile Smith Rowe sealed victory for the Gunners late on.
Arsenal captain Alexandre Lacazette was denied by former Arsenal goalkeeper Lukasz Fabianski during the second half.
West Ham’s Vladimir Coufal was dismissed for a harsh second yellow card during the concession of the penalty, when he bundled over Lacazette, despite seeming winning the ball first.
Coufal had incurred his first booking in the first half when his misplaced arm caught left back Kieran Tierney in the face, incurring vigorous protests from the Arsenal players.
Tierney went on to hit the crossbar, while further opportunities fell for Martinelli, Bukayo Saka and defender Gabriel as Arsenal thoroughly deserved their victory, showing that with the young guns on fire, it was a case of Auba who?.
