Alexandre Lacazette will undergo special surgery after losing his voice in interview

Alexandre Lacazette is set to undergo surgery to remove a small growth on his vocal chords, according to reports.

The Lyon striker's post-match interview following Sunday's 2-1 defeat to Monaco went viral on social media thanks to his high-pitched voice.

Lacazette spent five years in the Premier League with Arsenal and many were caught off guard by how different he sounded in the clip.

French publication L'Equipe claim the 31-year-old has been struggling to speak since the beginning of this summer due to a polyp, a growth of tissue.

Despite it being funny on the face of it, Lacazette is said to have been playing in 'severe pain' since returning to Ligue 1.

He decided to wait until the international break for surgery so he has time to rest before returning to training.

Lyon face Paris Saint-Germain on Sunday and after that comes the first international break of this season.

Since returning to Lyon, Lacazette has scored four goals in seven games and helped catapult Peter Bosz's side to fifth in the table.

Lacazette was Arsenal captain for the second half of last term following the departure of Pierre-Emerick Aubameyang.

He scored six goals all campaign however as the Gunners narrowly missed out on a spot in the Premier League's top four.

The 31-year-old chose to return to France upon the expiry of his contract and Arsenal replaced him with Gabriel Jesus, a move that's suited all parties.

Arsenal are currently top of the league and Jesus has scored three goals and provided three assists in six appearances so far.

Jesus won four Premier League titles with Manchester City but felt like a bit-part player for most of his time at the Etihad Stadium.

Arsenal manager Mikel Arteta believes a change in environment has helped the Brazil international's performances.

Arteta explained last month: "Obviously we had to change his role and what he had to do in this football club and now he's one of the leaders.

"He's a natural leader, but he's also somebody that is prepared and I think is in a stage of his career where he's able to do what we are demanding him to do.

"That's what he needed. Obviously he's played a lot of games in this league in the last few years but not that many as a starter, especially in the last two years.

"He really wants to feel like the player that can make the difference for the team and that's the next stage."
