Chelsea took a giant step towards the last four of the Champions League with a resounding win in the quarter-final first leg.
Mason Mount and Ben Chilwell scored priceless away goals in Seville, where both legs of the tie are being played.
Mount opened the scoring with a superbly-taken goal just after the half-hour mark.
He collected Jorginho’s clever through-ball and turned away from Zaidu Sanusi before firing low into the far corner of the net.
Cesar Azpilicueta missed a great chance to double the lead when he headed Reece James’ free-kick wide of the target from close range.
And Christian Pulisic, on as a substitute for the Blues, fired against the underside of the bar shortly before Chilwell netted in fine style late on.
Chilwell pounced on a mis-control by Jesús Corona, raced past defender Chancel Mbemba and rounded keeper Agustín Marchesín before slotting into an unguarded net.
