Mesut Ozil Back in Training Ahead of Arsenal vs. Atletico Madrid

Arsenal have been handed a fitness boost ahead of their UEFA Europa League semi-final meeting with Atletico Madrid, as Mesut Ozil took part in training on Wednesday. 

Ozil missed the match with West Ham United in the Premier League on Sunday due to illness, sparking fears he could be absent for the crucial showdown at the Emirates Stadium on Thursday.

However, as reported by ESPN's Mattias Karen, the German playmaker, Jack Wilshere and Petr Cech all appear ready to feature in the game if needed:

Ozil has been one of Arsenal's standout performers in an otherwise difficult campaign, and his ability in possession will be crucial to the Gunners breaking down one of the best defences in world football. 

Without their No. 11 at the hub of the side, Arsenal struggled for long spells against West Ham on Sunday before a late flurry saw them win 4-1. As noted by James Benge of the Evening Standard, Ozil has been absent with illness a lot lately:

Although he's often criticised for his languid style, when he's at his best Ozil is one of the top attacking midfielders in European football.

In the previous round, he excelled in the home leg against CSKA Moscow in a 4-1 win for the Gunners, dominating the game and picking up two assists. Per OptaFranz, he's made good contributions in the competition this season:

Additionally, as relayed by OptaJose, during his time in Spain the former Real Madrid man had a habit of netting against Thursday's opponents:

Although apathy has swamped Arsenal after a poor Premier League campaign, the atmosphere should be electric for the visit of Atletico.

Not only is it the semi-final of a European tournament, it's the last huge tie manager Arsene Wenger will have at the Emirates Stadium before he leaves the club at the end of the campaign. If Arsenal are to grab a memorable win, Ozil will surely be central to it.
