It's not easy to sign players that directly improve the team when you're one of the best 8/9 sides in Europe.
With Christensesn returning and Rudiger coming in we have improved in 2 of the 3 defence positions.
We have a better backup keeper than we did last season.
We now have a better backup striker than we've had for at least a couple of seasons.
We've signed two PL proven HG players.
We've added a second option at both RWB and LWB that the squad was lacking.
And if you take out Caballero and Giroud, who were both signed for specific relatively short term purposes, the ages of the other 6 signings are 24, 22, 27, 24, 25, 23, 24 so maybe just maybe they deserve a little patience from fans to adjust, learn and develop both as footballers and humans when most of them are moving to a different culture and lifestyle as young men.
