The 27-year-old attacker will move to California for a reported $5m (£4.1m) fee from Ligue 2 Saint Etienne and follow the likes of Welsh superstar Gareth Bale to the MLS club.
It follows claims from French media ahead of the weekend that Rangers had enquired about the 32-times capped Gabon star amid interest from several other European clubs [Le10Sport].
The report claims that Rangers were joined by the likes of Belgian sides Anderlecht and Club Brugge in tailing the winger but claimed then LAFC was his most likely destination.
This has now been made official with Denis Bouanga set to turn out in the MLS where he will come up against the likes of ex-Rangers utility man Matt Polster.
Rangers-linked Denis Bouanga could face Matt Polster after LAFC move
Polster, 29, is now a key player for New England Revolution and the former Chicago Fire star was back amongst the MLS headlines this weekend.
The Steven Gerrard signing netted the opener in a thumping 3-0 win for the Revs away from home against Orlando City.
The midfielder showed good control to receive a nice pass at the edge of the box and finish calmly into the bottom corner.
As for Denis Bouanga, Rangers have undergone a summer of recruitment and perhaps the winger was amongst several options at Ibrox.
In the player’s position Rangers have signed the likes of Tom Lawrence and Rabbi Matondo and perhaps these options were seen as better value for money.
Many still believe Rangers need another attacking option in the squad and it’ll be interesting to see if the club do move in this area as the transfer window enters its final few weeks.
