Help with Leicester promotion push!

[FuriousFox46]

I think I've had a pretty decent start to the season but have hit a poor run of form... I'm now 7th after 19 games 3 points off the play-offs. I'm still confident I'll get promoted since we were playing excellently before the last couple of games and I've already played all of the top 15 sides. But we seem to drop points to **** teams like Doncaster we drew 3-3 with. Other than that had a cracking cup run which ironically ended at home to Man City (beat Crewe, Cov and Spurs on the way) Sheff Utd and Ipswich are the top two.
Here's my team and the 3 formations I use during training any recomendations would be greatly appreciated;
