Why Does Bendtner come on....

As i was watching the game against spuds, i was expecting the appearance of andrey arshavin at a point in the game, i was shocked to my brains that Nasri and Theo were brought off and bendtner came on which made me think "What special stuff does this guy do in training that doesn't reflect in matches" and he obviosly hasd no contribution to the game at all and so was the game against liverpool. So as our title challenge is over now, i just hope we come second in the league and avoid slipping lower in the league table... and hope for a better next season.
