Mason Mount and Ben Chilwell's first Champions League goals saw Chelsea beat Porto 2-0 to seize control of their quarter-final first leg in Seville.

Chelsea travelled to the Ramon Sanchez-Pizjuan in desperate need of a response to Saturday's drubbing at the hands of West Brom, and Thomas Tuchel's side delivered.

Mount opened the scoring shortly after the half-hour mark, exquisitely controlling Jorginho's pass before finishing into the far corner to open his account in Europe's elite-club competition at the 15th attempt.

On a night of firsts, Chilwell followed in Mount's footsteps with a stunning first Champions League goal as he intercepted a stray pass, drove into the area, and rounded the Porto goalkeeper five minutes from time.

The victory and two away goals leave Chelsea in complete control of the tie ahead of next week's return leg at the same venue, where they aim to reach the semi-finals for the first time since 2014.

Man of the Match: Edouard Mendy

Porto were without their two highest scorers Sergio Oliveira and Medhi Taremi through suspension but fashioned the early chances in Seville and should have had something to show for it.

Luis Diaz forced a block from Andreas Christensen in the Chelsea goal mouth before Mateus Uribe's brilliant control and volley sent the ball looping onto the roof of the Chelsea net.

Porto went even closer midway through the half when Pepe headed the ball back into the six-yard box moments after Chelsea goalkeeper Edouard Mendy hooked Otavio's direct corner from under his bar, but Zaidu Sanusi blazed wildly over from close range with the goal at his mercy.

Porto were left to rue the catalogue of misses just after the half-hour mark as Chelsea scored a crucial away goal.

A first concerted spell of Chelsea possession ended with Jorginho firing a perfectly-weighed ball into Mount, who pirouetted brilliantly in behind before firing his maiden Champions League goal into the far corner.

There was still time before the interval for Porto to create another opening, but Mendy preserved Chelsea's lead through to the break with a fine save from Pepe's near-post header.

Mendy had to be alert early in the second period to prevent Moussa Marega from punishing a defensive lapse from Antonio Rudiger, and it was all hands to the pump for Chelsea as Porto piled on the pressure in search of an equaliser.

Porto had the ball in the Chelsea net on 56 minutes, but Pepe's effort was ruled out after Chancel Mbemba was caught offside, moments before Diaz whistled a shot a whisker wide of the post.

Cesar Azpilicueta squandered a glorious chance to give Chelsea some breathing space when he headed Reece James' cross over from six yards, before substitute Christian Pulisic went even closer when he rattled the underside of the bar six minutes from time.

An advantage of any kind would have represented a job well done for Chelsea but there was more to come from their impressive performance as Chilwell intercepted Jesus Corona's stray pass, strode into the Porto area and coolly rounded the goalkeeper to put the seal on a morale-boosting victory which puts the semi-finals in sight for Tuchel's side.
