Bojan Krkic would have become Spain's youngest-ever international had he not suffered stomach problems before the kick-off of the friendly with France this month.

Although the 17-year-old, who is of Serbian origins, will not play at Parkhead, Celtic should be warned that he will be a threat if he is involved in the return leg.

He has superb close control, dribbling ability, pace and is clinical in front of goal - it is easy to see how he scored 889 goals in seven seasons with Barca's youth team.

Now mixing it with the likes of Ronaldinho, Thierry Henry and Samuel Eto'o, the teenager is more than holding his own.
