Ones to watch
The speedy winger has enjoyed a good spell in the Championship this season. The Senegalese international has eight goals and four assists in his 30 league games this season. His turn of pace is what has caused teams the most teams trouble, often leaving players for dead, but it's his end product that has let him down at times. However, in recent weeks he has shown glimpses of improvement, including an impressive double against Bristol City.
The former Watford man has two goals for the Reds this season with both of them coming against Wycombe on his debut. His all-round centre forward play also impressed the Forest faithful. He holds up the ball well and is able to draw many fouls in dangerous positions for the Reds whilst also showing great composure when needed.
Against William Troost-Ekong, it will be interesting to see who will come out on top in the battle between two very experienced players.
The two sides met earlier in the season playing out a 0-0 draw at the City Ground. Over the last five encounters, it is all square with three draws and one win apiece. The last game between the sides at Vicarage Road ended in a 2-2 draw with Odion Ighalo and Matej Vydra scoring for the Hornets and Michail Antonio for the Reds.
