Nottingham Forest manager Dougie Freedman has already made tactical changes to the side since taking over.
Freedman was brought in to replace Stuart Pearce back in January and he has made a hugely impressive start to life at the City Ground.
Forest are unbeaten in the five matches they have played under his stewardship and it is by no coincidence, as he has changed so much in such a short space of time.
Freedman has made Forest much more robust and efficient, although he has had to reduce the style of the team.
The Scot has made the Reds much harder to play against, with teams struggling to come to terms with their newfound structure and shape.

Forest are making considerably fewer passes per game under Freedman than they were under Pearce, but they are having more shots and using possession more wisely.
It is also noticeable that they are making far more interceptions now. This suggests that they are organised and pro-active, with each player having a distinguished role in the team.
Under Pearce, Forest had proven to be frail and easy to break down, but Freedman has had a huge impact already and they are starting to look like a team capable of competing at the top of the table.
Forest are currently 12 points off a play-off spot, but if they can keep improving whilst ensuring results stay positive then they may have an outside chance of promotion this campaign thanks to the drastic changes Freedman has been able to implement so swiftly.
