Yoki if the Sanchez transfer goes through can he help us by playing at RW? We currently have a hole a that position and I hope an Arsenal fan can fill me out on Sanchez. Also you'll love Micki, he didn't fit in well with Man U but he'll be great in Arsenal.
He can play pretty much every attacking position on the pitch. I think he'll slot well at the right wing spot. He can make runs from the wide spot, he can get the ball and be a service guy from the wide too, and he can surely go one on one from that wide spot as well.
You're only concern with him will be is that he gives up the ball a little too much. But that could just be because Arsenal doesn't know proper positioning. He's too competitive as well, and that could rub teammates the wrong way, although, that could just be Arsenal not being used to playing with a guy who has a lot of fire and passion.
You guys are getting a great player, and I hate that he's going to you guys, but it's better to get something from him than lose him on a free.
