If Ndombele and Lo Celso will come and we can do deals, I'd sacrifice any other signings this summer to get them. They'd completely rejuvenate our team alongside fitter players, who haven't just come back from a World Cup.
I'd willingly give Aurier/Trippier another season and take a chance on playing Dier/Foyth more at centre back, if Toby leaves, to get that kind of quality in the middle of the park.
However, if a PSG or Citeh come in with a ridiculous offer, we're going to struggle, no matter how early we make a bid or how high or low we pitch our first one. PSG wanted Mbappe and Neymar and they simply outbid the world to get them. We're not able to get anywhere close to that kind of finance, but we did take Davinson Sanchez when Barcelona were interested and Juan Foyth, when PSG were favourites for his signature. It is possible.
