Arsenal striker Pierre-Emerick Aubameyang should be fit to face Villarreal on Thursday, per the Daily Mirror.

The Gunners face their biggest game of the season, and arguably of Mikel Arteta's tenure at the club so far.

Arsenal are 2-1 down from the away leg in Spain, and must win at home to progress to the final.

The Europa League is likely the club's only way of securing European football for next season.

Aubameyang, who has 15 goals from 35 games this season, is working on his fitness levels after contracting malaria last month.

He was in the starting lineup against Newcastle United on Saturday, and if he has no reaction in training this week, should play against Villarreal as well.
