Coquelin was on loan at Charlton and surplus to requirements before injuries to Aaron Ramsey, Jack Wilshere and Mikel Arteta forced Wenger to recall him - planning only for him to be back up.
But after Mathieu Flamini also picked up a knock, the 23-year-old was given his chance and hash't looked back.
Kondogbia scored Monaco's opener as they shocked Wenger's side at the Emirates, and reports suggest the French side would be willing to sell for as little as £14.5m this summer.
Ozil, whose return from injury last month boosted Arsene Wenger's side, has often come in for criticism.
“You speak about Arsenal and how they don’t spend big money on a player often but they did with (Mesut) Ozil and it is always a bit risky,” said Silva. “Coming from Spain it is tough to adapt, it doesn’t always happen straight away.
“I think the most important thing is that the player understands the philosophy of the team, the philosophy of the manager and the expectation from the fans.
“I do really like him as a player but sometimes in the game he does look quite slow, although he has that quality to change the game.
“He can be more decisive for Arsenal for the quality he has, he can be much more decisive for the club."
Arsenal, who signed Gabriel Paulista in the January transfer window, are still looking to bolster their defence and Umtiti - who has helped Lyon to the top of Ligue 1 - is on reportedly Wenger's radar.
