Best and worst transfers of the summer?

I know it's early, but I thought it'd be fun to talk about the best and worst transfers of the year so far. My favorites are:

1) Mesut Ozil to Arsenal. He and Olivier Giroud will combine to do significant damage to Premier League goalkeepers' egos this winter. IMO he is the best CAM in the world right now.

2) Ricky van Wolfswinkel to Norwich City. He is exactly the type of player the team needs up front, and if they sack up and employ a more aggressive approach I think he will turn into this year's Michu.

3) Pierre-Emerick Aubameyang to Dortmund. He will ultimately replace Robert Lewandowski, but for now he's making the loss of Mario Goetze much easier for Dortmund fans to stomach. He will be a very good one for the Busy Bees.

My least favorites are:

1) Thiago to FC Bayern. My favorite team spent over 20 million Euros on a guy that, frankly, we just don't need. This is a real head scratcher to me.

2) Neymar to Barcelona. Why on earth did they do this? The side needs defenders in the worst way, and I'm pretty sure they're covered at striker even without Neymar.

3) Clint Dempsey to Seattle Sounders. He was doing just fine in the UK, and his experience there would only help the US progress in the WC.
