Our current players are knackered. The amount of playing time our front 5/6 are getting is beginning to show. We are missing Gundogin to provide relief for KDB etc. Sane is not as 'hot' as he has been and Sterling has been through a dip lately. Mbappe, Sterling, Sane, Jesus and Kun could carry the frontline with fatigue and injurys and everyone be kept happy. A purchase in this area is essential not a luxury.
I agree. That front 3 formation is incredibly physically demanding. There's no chance that we could expect the same front 3 to play all of the CL games nearly all of the PL games and their international commitments. That's not even taking into account the domestic cup games.
