Wilshere has yet to feature in a competitive game this season after suffering a broken leg.
The England international midfielder is on his way to recovering full match fitness, and Chambers is delighted with the progress the 24-year-old is making.
Wilshere is a talented footballer, but his progress in recent years have been impeded due to injuries.
Now that the midfielder has started training, he will be keen on getting some valuable playing time between now and the end of the season.
The Arsenal man will be determined to prove his fitness in order to be part of the England national team for the Euro 2016 finals in the summer.
Arsenal are third in the Premier League table at the moment with 55 points from 60 matches, 11 points behind leaders Leicester City with a game in hand.
