It's easy to romanticise about the past. I remember that Palace game well. We weren't swashbuckling at all. It was an arduous game that we won through persistence.
The last 25 mins of last weeks game vs Palace was more entertaining than that entire game in April 2017
There were plenty of games mate. Needed a penalty to beat Boro at home. Which came a few days after failing to break down Sunderland. Both teams got relegated...
There was Swansea away, which we all remember fondly because we won 3-1 with three last minute goals, but for 80 odd minutes we couldn't break them down... The Palace games you mentioned. Then there was the spell when we had no Harry where we drew about 3 games on the bounce.
Unfortunately, the better you get and the more fear you give opponents, games can go one of two ways. They sit back and make things tricky, or the opponent admit defeat before you take the pitch. We're not quite at the second level yet until we can prove to make games like Palace a norm. That's not easy to do after 8 months into a new system.
