Youngs pace is a great asset to villa style of play and any counter attacking side.
Arshavin though has got the footwork, positioning and passing ability that fits really well in the arsenal side. I couldnt vote for arshavin because i feel that need to see him play a full season before can judge. I feel that he couldnt play consistantly good for a full season of 2-3 games per week.
Would like to be proved wrong even though it would make arsenal a tougher competitor because I like to see good football and when he is on form he is enjoyable to watch.
