4. Attack
Alexandre Lacazette is set to be the main striker for Arsenal this season. Danny Welbeck should also find a space in the teame. Despite being injury prone, his experience can always help the squad.
Che Adams is the last transfer on this list. The striker already banged in 21 Championship goals in this season, and at only 22 years old, the pacey striker still has plenty of potential in him. Adams is also able to play on the wing, which could make him valuable for the further campaign. Birmingham seem to value him at £10-15 million, which makes him look like a true bargain.
This is how the team sheet would look like after such a summer:
GK: Leno, Martinez, Walton (HG)
RB: Bellerin (HG), Clyne (HG), Maitland-Niles (HG)
CB: Sokratis, Ginter, Holding (HG), Koscielny, Mavropanos
LB: Kolasinac, Bernardo
CDM: Xhaka, Guendouzi, Torreira, Chambers (HG), Bennacer
RW: Costa, Nelson (HG)
CAM: Fornals, Suarez
LW: Aubameyang, Iwobi (HG)
ST: Lacazette, Adams (HG), Welbeck (HG)
Bold: New transfers, (HG): Homegrown
All the transfer values came from CIES, combined with the price listed on transfermartk.co.uk and the players standing in the club.
