My arguments against making Europe are the following:
1. We would need to sign 5 or 6 players better than what we already have to be able to compete on both fronts and allow Wilder to make the changes he'd need each game to compete in the league and Europe. That would cost a lot of money in not only fees, but wages too. Money we don't yet have without risking the long term stability of the club.
2. If Wilder did bring in 5-6 players who could replace the existing players it could upset squad harmony and the balance we have in the team. We have a unique system that's taken McBurnie and Berge a while to get used to. Our success under Wilder has been keeping a team together and strengthening one or two positions at a time. Wholesale changes expecting new players to understand and play in our system could be our downfall.
3. The new season will kick off only a few weeks after this season ends. European qualification will resume in something like just two weeks after the season ends. Teams already competing in Europe now and next season will practically get no break. Teams qualifying for Europe next season will practically get no break. They are going to burn out next season, drop lots of points and fall down the league table. By not qualifying for Europe we can get a decent break, take advantage of others burning out and exploit this in the league in the hope of finishing higher next season.
That's just my take on it.
One more season in the Premier League, stability, slowly build a squad and team capable of competing on two fronts, a push for a domestic trophy and worry about Europe the season after for me please.
