Your first sentence is fluff as it make no sense re. what I wrote.
"It is conceivable that City could lose Mahrez, Gundogan and Walker — as well as Aymeric Laporte and Joao Cancelo — in this window while bringing in just two players."
At this moment in time (emphasis on this moment in time) he would be quite right.
Cancelo we all know about and barely qualifies to be included in that list, Mahrez was benched for the Bayern QF games onward and pretty much kept for the PL games run in. Laporte got a lot less than that, so we've now got Kovacic & Gvardiol in (Gvardiol is done as far as I'm concerned) and Walker so far is still here (as is Cancelo & Laporte but I'd be surprised if they're still here when the window closes).
So highlighting the sentence you did makes no sense.
