Arsenal will look to get back to winning ways in the Champions League this week but they face an extremely tough task away at Sporting CP, who have been one of the most impressive teams in any league in Europe this season.
The Gunners lost to Inter last time out and could be doing with a win to propel themselves up the table, but Sporting have won every single home match this season and last time out in the Champions League, claimed the scalp of Manchester City.
Here's how the squads are shaping up.

Sporting CP vs Arsenal Expected Lineups
Some fans are viewing this as an audition of sorts for striker Viktor Gyokeres, who has been strongly linked with a move to Arsenal. He was only on the bench for the cup match at the weekend, but still came on as a substitute to score so he'll be restored to the starting XI.
With Goncalves, out, Marcus Edwards will likely continue in the front three.
Sporting (3-4-4) Israel; Reis, Inacio, Diomande; Quenda, Morita, Hjulmand, Araujo; Trincao, Gyokeres, Edwards
Declan Rice returned from injury at the weekend but was an unused substitute against Nottingham Forest so he is fresh and good to go here, and he'll probably replace Jorginho in midfield.
Kai Havertz, Thomas Partey and Gabriel Martinelli could return to the starting XI, too.
Arsenal (4-3-3) Raya; Timber, Saliba, Gabriel, Calafiori; Odegaard, Partey, Rice; Saka, Havertz, Martinelli
