Arsenal head into the game on a fine run of form but it will be interesting to see how Mikel Arteta prioritises this competition now the Gunners are doing so well in the Premier League.
Arsenal are 1st in the league but with just five points separating them and Manchester City, any sort of slip up could cost them their first league title since 2004.
Predicted Arsenal line-up vs Sporting
Arsenal team news vs Sporting
Gabriel Jesus is a long-term absentee and whilst this game will come too soon for the Brazilian, he is expected to return later this month.
Eddie Nketiah has an ankle issue that saw him miss Arsenal’s 3-2 win over Bournemouth at the weekend.
Speaking last week, Mikel Arteta has this to say on the striker: “We are assessing [Eddie], and it’s a bit uncertain what’s going to happen with him, to be honest. Let’s see and keep the options open. He’s very positive about it, so hopefully, he will be fine.”
Arsenal may need Nketiah back pretty soon, though, as Leandro Trossard picked up a muscle injury vs Bournemouth and is expected to miss this tie.
Mohamed Elneny also remains sidelined with no return date.
