The Arsenal website is reporting that the Under-21s match on Tuesday night between the Londoners and Stoke City is set to be an opportunity for four of the club's first team squad to edge closer to a Premier League return.
With all four operating in midfield, the group will have been devastated at missing out on the Gunners' impressive form in the league, where they have won seven matches in a row, and may well find it tough to win back a place in Arsene Wenger's side.
After a strong campaign last year, Jack Wilshere will be disappointed to have played just 16 times this season, and has seen Santi Cazorla drop deeper into midfield to claim what was arguably the Englishman's position.
Despite Arteta being captain at the club, the Spaniard has had to sit out much of the season himself since suffering an injury in the 2-0 win over Borussia Dortmund in November. Now 33-years-old, and with just 12 appearances to his name as Arsenal look like having their finest league campaign in over a decade, the former Everton man's star may be in decline.
Diaby's absence hasn't been much of a surprise, with just two appearances in the last two seasons. He has had thigh muscle issues all year, and only featured in the League Cup loss to Southampton, but with his contract set to expire this summer, he more than anyone will be keen to prove his fitness and quality.
Gnabry's lack of playing time this season will have been a disappointment for Wenger, after the young German had something of a breakthrough campaign in 2013-14, making 14 first-team appearances.
