Claudius adding more strong players will give the team more resilience, but i really believe we have an exceptionally strong core.
We have a fairly fit and robust core. Saka, Timber and Ødegaard are our current big worries as far as injury and level. Getting Partey out of the road should be a massive risk mitigation. White and Havertz may not be guaranteed first choice, both are also a risk but a lesser risk. Then there are our perma-crocks such as Tomiyasu and Jesus.
Where we might end up in last season's horrible territory would be if Zubimendi did his ACL training over-zealously in preseason. We do need to let the man adapt to England a bit.
