ye i'm having exactly the same problem, playing in League 1 with Rotherham and have just come off the back of throwing a 2-0 half time lead to a team 10 places below in the league, after telling the players to keep focussed and getting 10/11 positive motivated and focussed reactions from the players, losing the game 3-2 in the second half. I'm 5 games from the end of the season and worked out that i've lost 35 points from winning positions over the course of the season, throwing a 2 goal lead on 3 occasions . Switching to a contain mentality with virtually all the players set to defend deep isn't making any difference.
