Made an absolutely stunning save in the latter stages to deny Jonas but any good grace from his performance fell away when he deliberately got Alcacer booked by going down too easily, meaning the Valencia striker will miss the second leg.
Displayed decent attacking ambition down the right-hand side and was always looking to get beyond Reyes on the overlap. However, almost cost a goal with a horrible clearance to Vargas on the edge of the box.
Constantly put out fires in the middle of the park and provided a decent insurance policy just in front of the defence. Drifted in and out of the match as the game went on, though.
Was a massive threat from set-pieces all night and arguably should have scored two in the first half from headers, but sent the first wide and saw the next attempt saved by Guaita. Aerial dominance also aided in defence.
Positioning was spot on throughout and was usually in the right place at the right time to clear away crosses into the box. Marshaled Alcacer well and didn't allow the strike much time to turn and get shots away.
Wasn't particularly effective in an attacking sense but had his hands full with the pacey Vargas coming in from the right. Lost the Chilean a few times but ultimately remained solid and dependable at left-back.
Drifted in from the left-hand side and was a constant threat as Valencia failed to track his nomadic runs into central areas. Won the free kick for the opening goal and assisted Bacca's goal with a lovely one-two.
Drifted in at the back post and made up for an initial misjudgement to cleverly backheel the ball into the corner for the opening goal. Made some powerful runs through the middle and was particularly effective on the counterattack.
Was a great creative influence for his side for the entire match and all of Sevilla's positive play went through him. Oozed class when on the ball and the only thing his performance lacked was a goal or an assist.
Spurned a great opportunity to put his side ahead midway through the first half but made up for it with a fantastic finish into the bottom right corner for the Sevilla second. Should have got two or three more but worked so hard.
José Antonio Reyes
Put in an excellent defensive shift as he helped out Diogo all night with the overlapping runs of Bernat. This fatigued him and hampered his attacking ambitions though, as he was pretty ineffective going forward.
Could have did nothing to prevent either of the first half goals and even kept the score a two before the break with a brilliant stop to deny Fazio. Had a running feud with Bacca and frustrated the Colombian with two top saves.
Attempted to organise his defence as best he could but his message just didn't seem to be getting across. Made some decent interceptions and almost clawed a goal back for his side with a free kick that was whipped wide of the post.
Got into some decent advanced positions down the right-hand side but his delivery wasn't up to scratch. Was much better when cutting inside and picking out passes, which he did effectively. Struggled against Vitolo, though.
Showed some glimpses of his pace in the final third but stupidly pulled the arm of Vitolo which lead to the set-piece for the opening goal. Second half was poor and he never really looked like picking out an incisive pass or harming the goal.
Was neat in possession down the left-hand side but was guilty of often reverting play back to the left-back and offered very little penetration. Withdrawn before the hour mark for Piatti.
Was lucky not to get booked early on as he went flying in to a number of challenges as Valencia looked to start at a high tempo. Was not up to his usual standard on the ball, and was rather lackadaisical in dangerous positions.
Was superb for the opening 20 minutes and looked dominant and comfortable in the middle of the park, but he Sevilla midfield eventually overran him and he looked powerless to resist. Drifted out of the match terribly as the time went on.
Was constantly being pulled out of position by the runs of Bacca, which lead to the second Sevilla goal. Was extremely lucky not to give a penalty away as he used his hand to deny a Gameiro volley, especially since he'd just went into the book moments before for the same offence.
It was quite incredible that he didn't go into the book in the first half as he committed a number of poor fouls, including two or Rakitic alone. Brought off at half time after a nasty clash of knees with the Croatian.
The biggest threat that Valencia had on the night. Latched on to a mistake from the Sevilla defence to whip a shot towards the far corner that went inches wide and then crashed a header off the bar in the latter stages.
Didn't see much of the ball in the first half but did test Beto from the edge of the box with a stinging strike towards the left corner. Wasn't able to find space or become more of a threat and will now miss the second leg after an ill-advised challenge on Beto.
