I don't care who your manager is, no coach is making Sanchez & Dier a title challenging CB pairing. I also don't think we are strong enough in CM due to Ndombele's inability to scale the heights expected of him.
Mourinho didn't work out, that much is patently obvious, and yet his strength historically was making his teams hard to beat. Defensively sound. And he couldn't do that with our defensive personnel.
The Romero signing will help if that happens, certainly, but will it be the silver bullet to fix our defensive woes? Definitely not. Our full backs are both suspect too.
I admire your optimism but having lost Bale and moving on Toby and thus far brought in just a prospect for the future in Gil I see us as weaker if anything than last season, whilst some of our rivals (Leicester, Liverpool,United to name a few) have strengthened this summer in comparison.
Top 4 is going to be a real struggle, albeit i think we will give it a decent go, however the Kane distraction doesn't help matters
