The Spanish side controlled most of the match after that to hand Brendan Rodgers' side their first defeat of 2019, ending a run of seven straight wins, and leave the Scottish champions all to do and more in Spain next Thursday.

The night began with a minute's silence in tribute to Emiliano Sala, the 28-year-old striker who recently died in a plane crash when he was flying to join his new side Cardiff.

Celtic, who had fit-again left-back Emilio Izaguirre back in the side, started with purpose.

Attacker Ryan Christie's early drive from just outside the box failed to really test Neto but moments later Valencia's Brazilian goalkeeper did well to parry a more powerful drive from Callum McGregor with defender Lato completing the clearance.

Lato had earlier elicited penalty claims from Celtic after tangling with winger James Forrest inside the box but Romanian referee Ovidiu Hategan was unimpressed.

Sobrino, the January signing from Alaves, partnered Cheryshev in a 4-4-2 formation and the duo watched the Valencia defence repel a stream of attacks before later really making their mark.

However, in the 18th minute, following a cross from the right from midfielder Carlos Soler, Sobrino flicked on and Daniel Wass' header had goalkeeper Scott Bain stretching to claw the ball past the post, with the home side defending consecutive corners.

Skipper Scott Brown's short pass back to Bain seconds later almost had his side in trouble again and the Spaniards grew further in confidence as the first half unfolded.

Nonetheless, Parkhead was stunned in the 42nd minute when Valencia scored on the counter-attack.

When McGregor lost possession in the middle of the park, skipper Daniel Parejo sent Sobrino racing clear and he simply laid it off to Cheryshev to tap into an empty net from close range.

Former Arsenal midfielder Francis Coquelin replaced Parejo for the second half and four minutes later the Hoops were two behind.

Cheryshev raced down the left and crossed for Sobrino to volley past Bain from six yards, adding to the despair of the home fans who had claimed the Russian was offside.

Just before the hour mark Rodgers went for broke, bringing on strikers Timothy Weah and Odsonne Edouard for Scott Sinclair and Christie respectively.

The Hoops fans tried to drive their team on but Valencia held firm under occasional periods of pressure and their hard work and organisation allowed the match to fizzle out, with Celtic requiring quite a turnaround in the return match if they are to reach the last-16 this season.
