Hopefully we will fill up the gaps(RB & CM) in the summer, this current midfield simply gets dominated physically, i woudn't be surprised if we go after Spurs's Dembele next summer for example tbh, not that i am very fond of him personally, just that literally almost any physically imposing CM can probably do a better a job than what Khedira or Matuidi had to offer last night...
I don't want to be too harsh on Blaise, pre-injury Matuidi seemed like exactly what we were missing to make this 4-3-3 work, tho this half-fit Matuidi leaves a lot to be desired... nonetheless i think he will eventually bounce back to his usual self sooner rather than later, so that's a good sign.
All in all, next mercatto will tell us more about how far we aiming to go.
For now, let's just enjoy this win and hope we will have a fully fit squad going into the Q-F.
