Once again,Sydney acquitted themselves well on the Asian stage. They were energetic from the outset at Al Janoub Stadium,in Al Wakrah,Qatar,moved the ball with confidence,and took the game to the newly-crowned South Korean champions.
But when it came to putting the ball in the net - the only true measure of success in football - they were found wanting.
It was a reprise of last week's 2-1 loss to Shanghai SIPG - or,really,take your pick of pretty much any game the Sky Blues have played in Asia over the last two years.
The final five minutes of the first half summed it all up. Sydney should have taken the lead when right-back Rhyan Grant centred the ball and found an unmarked Trent Buhagiar,positioned a few metres away from the penalty spot and with more than enough time and space to provide the finish.
But the Olyroos striker dragged his first-time effort wide of the mark - and then four minutes later,at the other end of the park,Jeonbuk made it look easy.
In reasonably similar circumstances to Buhagiar,Na Seong-eun lost his marker,received the ball and then drilled it into the bottom corner with brutal efficiency. It was his first ever professional goal.
