Head coach Steve Cooper has some big selection decisions to make as Nottingham Forest prepare for their return to action.

Injuries could have a bearing on Cooper's starting XI to face Luton Town on Saturday. But he also has a dilemma about how to set his team up.

The Reds go into the game looking to halt a four-match winless run. They recorded a second successive draw last time out with a goalless stalemate away to Crystal Palace just before the international break.

At Selhurst Park, Forest stuck with the 4-3-3 shape they had deployed against Brentford. Going with four at the back seems to be Cooper's preferred choice, but he does want his team to have flexibility in formations so there could be the option of switching to a 4-2-3-1.

The latter would allow the Welshman to utilise another attacking player as the Reds work on creating more chances and scoring more goals. It would come at the expense of a midfielder, however - and the centre of the pitch is an area where Cooper has struck a nice balance with the trio of Orel Mangala, Nicolas Dominguez and Ibrahim Sangare.

In the absence of striker Taiwo Awoniyi, it was Chris Wood who got the nod to start against Palace. But for all their positive play, the visitors didn't exactly provide him with a great deal of service.

That is something Cooper will no doubt bear in mind for this weekend as he weighs up who should feature out of Morgan Gibbs-White, Anthony Elanga and Callum Hudson-Odoi - or whether all three should be deployed in attack. Divock Origi is yet to start a game in the Garibaldi so could provide an alternative to Wood up front.

At the opposite end, Forest could find themselves limited on full-backs. Gonzalo Montiel is a doubt after suffering a calf injury while on international duty with Argentina and Serge Aurier is in the same boat after being forced off in the capital.

Cooper said there has been no change to the situation of Nuno Tavares and Ola Aina, who have both recently been sidelined. It could mean Harry Toffolo keeps his place at left-back, while Neco Williams might find himself called into action if Aurier and Montiel are ruled out.

Predicted Forest XI (assuming those classed as injury doubts are not fit): Turner; Williams, Boly, Murillo, Toffolo; Sangare, Dominguez, Mangala; Gibbs-White, Wood, Hudson-Odoi.
