Based on Tolmie's tweets from the last few days I'd say the most likely scenario is Nunes + Felix (loan) or Barco, and Phillips (loan) going the other way. Obviously Felix the least likely of this scenario but we have no better inclination. I think the Eze ship has sailed. If Nunes doesn't work out then I reckon Joao Paulinha from Fulham will come in.
Bringing this window to:
In: Gvardiol, Kovacic, Doku, Felix/Barco, Nunes/Paulinha
Out: Laporte, Gundogan, Cancelo, Mahrez, KP
That is how you refresh a treble winning side. Txiki again proves he's the fucking man.
