It's all to play for on Thursday as Arsenal vs Sporting CP in the second leg of their Europa League last 16 clash.
Last week's meeting between these two in Portugal ended 2-2 and so, with no away goals these days, it's a real winner-takes-all affair as two of Europe's most famous sides battle for a spot in the quarter-finals of the competition.
Arsenal head into this one having thumped Fulham 3-0 last time out, but Sporting are full of confidence themselves after matching that scoreline at home to Boavista.
Mikel Arteta will likely continue his European rotation that will see the likes of Fabio Vieira and Takehiro Tomiyasu return to Arsenal's starting lineup, although the boss may keep more of his starters around in anticipation of a tricky game. With Crystal Palace on the cards at the weekend, it's a risk he can afford to take.
In terms of fitness issues, Eddie Nketiah's ankle injury continues to be problematic and Mohamed Elneny is also out for the season.
Arteta had ruled both Leandro Trossard and Gabriel Jesus out of the Fulham game, only for both players to feature – the former even started – so the Spaniard's team updates evidently must be taken with a pinch of salt.
Midfielder Hidemasa Morita, who scored the own goal last week, will not get the chance to atone for his mistake as he is suspended. But his place in midfield will instead be taken by the returning Manuel Ugarte, whose own ban is now over.
Centre-back Sebastian Coates is also suspended, while former Gunner Hector Bellerin will likely be denied a reunion because of a knee injury.
Arsenal predicted lineup (4-3-3): Turner; Tomiyasu, Saliba, Gabriel, Zinchenko; Jorginho, Partey, Vieira; Saka, Trossard, Smith Rowe.
Sporting CP predicted lineup (3-4-3): Adan; St. Juste, Inacio, Reis; Esgaio, Ugarte, Goncalves, Santos; Edwards, Paulinho, Trincao.
Adan; Inacio, Tomiyasu, Saliba, Jorginho, Partey, Goncalves, Saka, Trossard, Smith Rowe, Paulinho.
