The French international midfielder spent nine years at the Emirates Stadium, joining the Gunners as a talented 20-year-old from French side Auxerre in 2006.
After impressing as a youngster, Diaby became a key first-team play between 2008-2010 before succumbing to injury troubles which later blighted the remainder of his career in North London.
After making just one Premier League appearance in the past two seasons, both the club and player decided to end his affiliation with the Gunners with a new challenge already in store.
As per France Football, the 29-year-old has flown across the Atlantic and landed in Texas where he met up with Dallas representatives to mull over a tempting proposition.
“The French international could quickly resume service in the MLS. He is currently in Dallas and in advanced discussions with the sixth-placed side in the Western Conference,” the report states.
The one that got away?
In an era where Arsenal were badly crying out for a rock-solid defensive midfielder, they had arguably one of Europe’s finest in their ranks but unfortunately dogged by injuries.
Diaby has often drawn comparisons with club legend Patrick Vieira, with his strongest performances coming in the 2009-10 campaign where he managed to make 40 appearances in all competitions.
It’s difficult to say how much success the Gunners could have achieved with a fully fit Diaby patrolling the midfield, but his presence was certainly missed while absent with injury problems.
