The Spain international has not been in action since October 2016 due to an Achilles injury, prompting fears he would never be able to play at the highest level again.
However, the 33-year-old appears to have taken some steps forward in his recovery recently and doesn't seem to be too far away from a return.
"I've still got some way to go, because after being sidelined for 18 months, everything has to be done in its own time," Cazorla told AS (h/t the Press Association per the Daily Mirror). "But the sensations I have keep getting better and I'm feeling optimistic about the future.
"The objective is to play some part with the team before the season ends, but we have to take things carefully."
Cazorla added that being sidelined has been a "major struggle" for him. "When you have been out like I have, you also notice pains elsewhere—apart from what I've had with my tendon," he said.
In a video posted by Football.London's Charles Watts, Cazorla gave supporters a boost with a pre-match appearance on the field prior to their recent meeting with Atletico Madrid in the UEFA Europa League semi-final first leg:
The Gunners have missed Cazorla in the time he's been sidelined, as the former Malaga and Villarreal man is one of the most talented midfielders in the Premier League.
Prior to his injury, he was operating as a deep-sitting midfielder. That allowed Cazorla to get on the ball regularly and control the tempo of matches for the Gunners with his close control, in-game awareness and passing range.
Finding another footballer capable of doing that job quite so well is not easy. WhoScored.com's Ben McAleer summed up just how important Cazorla was to Arsenal's cause prior to his injury:
Arsenal supporters will be desperate to see Cazorla take to the field for the Gunners again before the end of the campaign, although it would be a huge risk to rush the Spaniard back at this point.
The big question is whether he will sign a new deal at Arsenal with manager Arsene Wenger departing at the end of the season, as his current terms are set to run out out at the end of the season.
Wenger said he's unsure what will happen, per James Benge of the Evening Standard:
It would be wonderful to see Cazorla involved in a competitive match again, as he's a joy to watch on the field.
If he can perform at a standard close to what he's previously showcased, he can still be an asset for the Gunners. Although the big problem for the veteran is that it's likely to take him a while to recapture his best form and fitness.
