Four months, 19 games and three managers. It's been a wild season at Nottingham Forest and Sean Dyche is only just picking up the pieces.

Nuno Espirito Santo's exit preceded a winless horror show under Ange Postecoglou, before Dyche delivered four wins and a draw in his opening eight games to move Forest out of the drop zone.

But Nuno's new club West Ham have the financial muscle to be able to strengthen in January and Forest, who also have a potential knockout stage run in the Europa League to contend with, cannot sit tight.

Here, our Forest expert TOM COLLOMOSSE answers all the burning questions that you need the answers to for the upcoming transfer window. 

1. What do Forest need to do in January?

Give Dyche the players he needs. Dyche feels Forest need improvement through the centre of the team and Daily Mail Sport understands he is not wild about his options at full back, either, especially with Ola Aina still out injured.

Recruitment was chaotic last summer and with a tighter window, Forest need to be extra careful before firing cash about as they did before the start of this season, which was two managers (and two different ethoses about how to build a squad) ago.

2. Do they have money to spend?

Forest certainly plan to invest. The relegation zone is too close for comfort and owner Evangelos Marinakis has not given up hope of winning the Europa League and winning an express ticket to the Champions League.

But how much they will have to spend is unclear.

This is purely speculative, but Forest could choose to invest again now and still abide by financial rules by making a key sale or two before the June 30 cut-off point.

Both Elliot Anderson and Murillo have admirers across Europe - the Manchester clubs have both been linked to Anderson but may wait until the summer to test Forest's resolve properly.

3. Who are they targeting?

As revealed by Daily Mail Sport last month, Brighton youngster Jack Hinshelwood is on Forest’s list. Hinshelwood can play either in midfield or at right back and has Premier League experience, meaning he would be able to slot in straightaway.

There was also interest in Albion skipper Lewis Dunk, though that never looked a realistic deal.

If Chris Wood does not start to make progress soon in his recovery from a knee injury, Forest may look for forwards to share the goalscoring load.

Top scorer Igor Jesus has seven goals, but only one of them has come in the Premier League, with no Forest player above three goals in the competition.

While there have been outbursts - most memorably in 3-0 wins over Liverpool and Tottenham - only woeful Wolves have scored fewer than Forest's 18 this season.

4. How have their summer signings fared so far?

A mixed bag. Jesus has been excellent and Douglas Luiz – when he has been fit enough – has looked good. Dan Ndoye and Omari Hutchinson have shown promise too. The picture is less rosy elsewhere.

James McAtee has made no impression whatsoever after joining for £25million from Manchester City, making only one Premier League start, while Nicolo Savona and Oleksandr Zinchenko have not convinced fully – just like Arnaud Kalimuendo and Dilane Bakwa, though the latter has struggled with injury.

Yet all judgments must be qualified. Forest have had three head coaches already this season and that makes settling into a new club very difficult.

5. And who might leave?

Kalimuendo has admirers in France and Italy and could be allowed to leave – but not if Wood and Taiwo Awoniyi continue to struggle for fitness.

Keep an eye on McAtee, too. The England Under 21s international does not seem the sort of player Dyche trusts and it is not hard to imagine him moving elsewhere, either to Germany or perhaps a club targeting promotion from the Championship.
