Why Yang may still feature heavily for Celtic - video debate

Despite having caps at U23 level, the 21-year-old had yet to make the step up to the senior squad. That changed in Wales last night, as the attacker made his first appearance for his country at the Cardiff City stadium in the country's capital.

Despite it being a cameo appearance - coming on in the 85th minute - it would have been a proud moment for the young winger, who has had a whirlwind few months since the interest from Celtic became concrete. This interest prompted a long and very public dispute between Gangwon FC and the player, which eventually resulted in a move to the Scottish champions.

South Korea boss Jurgen Klinsmann was full of praise for the winger, despite his little impact on the game as a whole. He said: "Yang has been playing well for Celtic and he came on here and was good too.

"I think it will be very important to see how much he grows and develops both at club and at country level. A lot of young players have joined and these players need to prove themselves with their performances. It is exciting to see the national team grow and develop with the addition of new players like Yang."

Fellow countryman and club teammate Oh Hyeon-gyu was also named on the bench for the 0-0 draw against Wales, but the striker did not see any game time in Cardiff, perhaps due to the striker just coming back from injury.

Join Ryan McGinlay and Alan Morrison in the video below, as they discuss this topic and much more in today's morning briefing, which is available to watch on YouTube.

The two contributors also go on to talk about how the season has gone so far for Brendan Rodgers and his side, as well as individual performances - both good and bad - in last Sunday's 1-0 win at Ibrox against Rangers. Plenty of discussion and opinion to be had, in what has been an interesting return to the club for Rodgers so far.
