I think a more apt example is Spurs in a PL context, they slowly climbed the rungs of the ladder to compete for the PL, CL, building a new ground with a strong history of player trading to enable them to get there.
Not sure many people have been to see Ajax, I have, they are a massive club. I think we are sometimes guilty of looking at other leagues down nose. Trust me competing for the Dutch title is very important in Holland. I would contend that no one in Amsterdam is bothered really about who wins the PL really, the 7th place battle or relegation. I think there is a tendency to be PLcentric. Apart from that, I could handle competing in the Europa League final and the Champions League the way they have this season, in essence whose to say the model doesn’t work, they are more successful then us historically and contemporily.
I’m surprised there is such debate over this, the reality is we have sold on almost all of our really best players for decades. Player trading in necessary and a reality for every club, bar none.
