In the context of where the club is, what you've said is what was necessary. Ashley, of course, didn't even do the bare minimum so we were left playing catch up.
So look I'm not saying the owners haven't done an amazing job, they have, because they were left in such a massive ****ing hole by that fat ****. What I'm saying is that in the context of what every PL club does every year (bar us and a couple of low-grade exceptions) is strengthen to consolidate. Ambitious clubs then push on. We've so far had to consolidate, because the players you mentioned were absolutely necessary; they've replaced Ritchie at left back (lols), Clark and Fede at CB, Hayden in CM, Darlow, then upgraded Krafth. Every one of those players has repeatedly looked like Championship level, being kind.
What's been done is amazing for the club. But in terms of where that will put us in the PL, we've done the necessary so far. Now, if/when we upgrade Fraser on the right and Wilson up front, THAT"S serious.
Does that make sense?
