I reject your reality, I substitute my own !!
Tielemans would be a big statement in my opinion, and I think Xhaka can rotate DMF role in this tactic as he is good positionally and has found a new level. Before this season I think not many would have said Tielemans is worse in a CMF/AMF role than Xhaka.Much prefer this line of thinking honestly. Hope it's something more aligned with this.
Good point on the midfield, we really need someone to at least semi-fill for Partey. If he gets injured for a month or more. We feel a lot more shaky
We still have Saka, Martinelli, Nketiah, Nelson, Vieira who can play on the wing. For Vieira it might be easier to play on the wing at this point rather than middle in EPL. Like I said, we will have many busses to break at the end of the season, and having Tielemans instead of Elneny or Sambi or even Vieira at this point, might help more than spending 70+ million on Mudryk who hasn't much experience himself so his performances are likely to go up and down.
I assume Arteta has soon seen enough of Sambi, and we have to be ruthless from now on as there are possibilities for it.
There was like that 25 million pounds to spend more last summer, so if we go for Mudryk, I doubt there is money for a midfielder, unless the transfer fee is in many many installments like Pepe was. Will be interesting to see what they do, I'm still happy either way, but we need some quality depth for sure, and even Arteta has said that.
