Former Tottenham midfielder Kevin O'Hara believes Arsenal are missing something after letting Trossard and Martinelli leave this summer, following their surprising elimination by League Two side Fleetwood Town in the League Cup.
After Arsenal's penalty shootout exit, Kevin O'Hara joined Arsenal supporter Francis on the Sports Bar show.
During the discussion, O'Hara explained: "I've been watching you this season, and listen, you know how to win Premier League games.
"I'm still not entirely convinced. I feel like you're missing something. I think you're missing Trossard a bit, and even Martinelli a bit.
"I think you're missing someone who can create something out of nothing."
Trossard left Arsenal in July for £16.7 million, despite providing 11 assists for the club the previous season.
