Arsenal are back in Europa League action tonight as they host Slavia Prague in the first leg of their quarter-final clash.
The Gunners simply must improve on their performance against Liverpool on Saturday as they were comfortably beaten 3-0 by the Reds.
Slavia will not be a pushover by any stretch of the imagination, as they dumped Leicester City and Rangers out of the competition in the last two rounds of the competition.
Mikel Arteta put his players through their paces in training on Wednesday ahead of the game, and there were some surprises faces spotted.
Defender Zane Monlouis and left back Joel Lopez were both spotted in training, and the same goes for goalkeeper Karl Hein.
The Estonian stopper was spotted in the background of one photo seen below, appearing behind Mat Ryan in one shot.
Hein being in action wasn’t a huge shock, but it does hint that he will be on the bench alongside Ryan on Thursday night, replacing Arthur Okonkwo.
Okonkwo replaced Hein on the bench for the second leg against Olympiacos in the round of 16, leaving some to wonder whether Okonkwo has leapfrogged him in the pecking order.

Yet with the Estonian in first-team training on Wednesday, it looks like he will be the one to join Ryan on the bench against Slavia – though Arteta will ultimately hope not to use him, as being down to his third-choice stopper would suggest something has gone horribly wrong.
