Kieran Tierney is in line to make his first Premier League start for Arsenal this weekend.
The fullback is yet to start a league game for the Gunners but is now ready after being eased back from injury.
The Scottish international was injured when he signed from Celtic in the summer after undergoing a double hernia operation which sidelined him for over six weeks.
Since returning from injury Tierney has only featured in cup competitions for Arsenal.
He made his debut in the 5-0 demolition of Nottingham Forest in the Carabao Cup and next appeared two weeks later in the Europa League against Standard Liege.
Many fans expected the 22-year-old to start against Manchester United but manager Unai Emery opted to leave him out.
The Arsenal boss also asked Scotland manager Steve Clarke to leave Tierney out of his squad for the international fixtures against Russia and San Marino.
Clarke respected the request and said: “Arsenal have indicated to us that they’d prefer us not to select him at this moment in time because he’d only played 70-odd minutes of football.
“You have to respect the club’s decision on that. I’d like to get Kieran in the squad and have him as part of the group but at this moment in time it’s more important that he gets minutes on the pitch and gets himself back to full speed.”
Emery used the international break to field returning players in a friendly against Reading.
Tierney featured alongside Mesut Ozil, Hector Bellerin and Rob holding as they continued their recoveries.
Arsenal sit third in the table and could leapfrog Manchester City with victory at Bramall Lane.
Victory would also see Arsenal secure back to back wins for the first time since the opening fixtures of the season.
