It is positive, he just needs work on decisions, like Stones and Ross.
Its times like this that should make him learn, mistakes when it maters. You just hope he has the mentality to learn from them.
I remember Barkely once trying a cross field ball in the centre of the park which was cut out and the opposition got the ball back and had a good chance from it.
Thats a good example of a young player who's not scared to try things ( a cross field pass which was underhit but could have helped us build an attack).
Trying to play a stupid flashy backflick in your own half that probably has more chance of going wrong that right isn't a good example of a young player who's not scared to try things.
You wouldn't say that if stones tried to dribble past 3 players in his own box, and it doesn't work for what Besic did.
It's like last week Mirallas tried a little flick to go inside his man but it didn't work and lost posession when he could have kept control but took a risk to get a good position. Thats fine, thats trying something with an upside.
What Besic tried had no upside than to make himself look good. And thats not what Premier League football is about unless you're actually helping your team out in the process by scoring or making goals.
