The striker market is better this summer than for many years. There truly will be no excuse if we don't sign one. Even leaving aside developmental players like Schick, Andre Silva, and Dolberg, you've got Belotti, Lukaku, PEA, Morata, Lacazette, and Moussa Dembele. All of them would walk into our team.
I think the demand side of the market is pretty favorable too. It seems increasingly likely that Costa stays with Chelsea and Aguero stays with City, which would take both those clubs out of the running and now Atleti won't be involved either with their transfer ban. Real will probably get Mbappe and Barca/Bayern/Juve are only likely to be in for cheaper players and prospects to backup their established star CFs.
So it seems plausible that the only really big clubs in the market with us will be PSG and United. Lets assume PSG signs Aubameyang and United signs Belotti or Lukaku. That still leaves four of the options listed above for us, with the main competition being Milan, BvB, and Liverpool, all of which we should be able to beat on wages. I think its pretty clear at this point that Wenger doesn't really rate Lacazette. But we should be able to have our choice of players like Morata, Dembele, and whichever of Belotti/Lukaku is not snatched up by Mourinho. There will be no excuse for getting beaten out for them by the likes of Milan, BvB, and Liverpool.
