Aubameyang, Mkhitaryan, Torreira, Leno, Guendouzi, Sokratis, Mavropanos and Lichsteiner. Wouldn't say its particularly disastrous to be honest. Aubameyang is probably their best player since Fabregas, Torreira was very highly rated, Guendouzi looks a good player but Arteta couldnt coach him, Sokratis is your standard decent solid CB, same goes for Leno as a GK, Mavropanos is a kid, Lichsteiner clearly just a punt on a bit of experience and Mkhitaryan was literally getting what they possibly could in return for Sanchez
