It was heartbreak for Celtic as Valencia sent the young Bhoys packing and progressed to the last-16 of the UEFA Youth League.
Jack Aitchison’s first-half goal was cancelled out by Ismael Martinez with minutes remaining to send the game to penalties as ‘keeper Antonio Sivera put the Spanish side through.
Valencia’s main threat Rafa Mir caused left-back Aidan McIlduff problems all evening with his pace and power but coped well to limit his capabilities.
Conor Hazard in the Hoops goal denied the Spanish side and Mir numerous times, including a close-range shot which he saved with his feet after a deflection.
Theo Archibald had Celtic’s first notable chance of the half after 23 minutes from Calvin Miller’s cross but Archibald fired well over the crossbar.
Celtic took the lead on 40 minutes through 15-year-old Aitchison after some lovely footwork on his debut at Paradise.
The youngster ran on to meet Jamie McCart’s terrific through ball that had the Valencia defence at sixes and sevens and skipped past the ‘keeper before firing the ball into an empty net.
Both sides continued to create chances in the second-half, the best falling to Celtic captain Fiacre Kelleher inside the box from Aitchison’s corner kick.
With just under 20 minutes remaining in the game Javier Jimenez was sent off for Valencia after a two-footed challenge on Aitchison.
Substitute Martinez lashed home on the 85th minute from 12-yards after the Celtic defence was stretched.
Innes Murray had a terrific chance minutes later to snatch the victory but his shot was fired straight at the ‘keeper.
So, after a disappointing loss, here are the player ratings from the game.
