Steve Cooper will be fretting over Danilo’s fitness, with the midfielder a doubt after coming off with an issue against Chelsea. Having utilised a three-at-the-back formation to combat Frank Lampard’s side, it may be that Cooper opts for a four defensively, which would accommodate a return for Brennan Johnson.
Arsenal have suffered another late-season injury blow with Gabriel Martinelli ruled out with an ankle injury. The forward limped off against Brighton and joins William Saliba and Oleksandr Zinchenko - who are both expected to miss the club’s last two fixtures - on the sidelines.
Nottingham Forest XI: Navas; Aurier, Felipe, Niakhate, Lodi; Yates, Mangala, Danilo; Gibbs-White; Johnson, Awoniyi.
