But Brighton was allowed to return to the game following an error via Karl Hein, Arsenal’s 20-year-old debutant goalkeeper. As he got here out of his goal to collect an overhit pass, Hein slipped. By the time he had regained his footing, the ball used to be past him. Down went Danny Welbeck, obviously fouled, and the Brighton ahead happily buried the resulting penalty against his former club.
Arsenal went on to dominate at the start of the 2nd 1/2 but Brighton carried masses of risk still, especially following the introduction of Japan international Kaoru Mitoma. The winger has been in thrilling shape in recent weeks and his end here, curled into the same nook that Nketiah observed in the first half, used to be a measure of his confidence.
Arsenal, with a game to chase, has been now leaving huge areas in their midfield. Brighton sensed the chance to counter and Tariq Lamptey’s searing tempo did the harm to their 0.33 goal. Billy Gilmour produced some pleasant work in the centre of the pitch, placing up the onrushing Lamptey, who completed underneath the diving Hein.
