Yeah pretty much.
But essentially they ignored strenghtening key central areas, Goalie allways been a sore point, having a proper CB (depth or starting) or not playing highline with a turtle like Mertesacker, MAIN WEAKNESS IN DM, and almost as important, not having a reliable top striker instead of likes of Wellbeck and Giroud.
1 down, 2 to go. I would said 3, but I doubt they will sign another CB since they signed that dude from Villareal mid season.
