It is true, teams tend to try to win Cup final against us, once they do, many games after they lose or draw, and it is not only with Erik, regardless how much you hate him.
10/11 season under SAF we lost against Arsenal 1-0 away in 35th round, only for them to lose against Stoke 3-1 week later, to Villa week after that and drew last game of the season with Fulham. 1 point in three games.
We won two (Chelsea, Blackpool) drew Blackburn. 7 poinst in three games.
2008, Arsenal wins 2-1, Rafael scored at the of the game. Arsenal lost 2-1 against Stoke again week later. Week after they had 4-4 with Spurs.
We won our next two games, Hull and WHU.
18/19 season under Ole Arsenal won 2-0, 30th game of the season. 8 games left. They went on to win 3 (Newcastle, Burnley, Watford) drew one (Brighton) lost 4 ((Palace, Wolves, Leicester and Everton)
19/20 Palace won 2-0 at OT, 36th game of the season, next 2 games loss (Wolves) and a draw (Spurs). 1 point.
Liverpool, after wining their Cup final at Anfield (you know which game) lost 2 (Bournemouth, City) drew 2 (Arsenal, Chelsea) and won 1 (Leeds) in the next 5 games. Leeds was the fifth game. 5 points.
We, in the same period of time lost one, drew one, won three. 10 poins.
Can go on and on with this play like Brazil 1970, win th Cup final against United only to drop lots of points after and play rubbish, but I have to work a little bit..
