The French star suffered the nasty injury late on in Les Bleus’ 1-0 win over Austria which left him bleeding profusely.
The incident occurred when Mbappe went to win a header but ended up inadvertently heading Kevin Danso’s shoulder.
Discussing the injury on talkSPORT, Chris Iwelumo declared: “His nose is definitely broken.”
The French Football Federation confirmed on Monday that Mbappe’s nose is broken.
The 25-year-old left the Dusseldorf Arena in an ambulance and has gone to the University Hospital of Dusseldorf to undergo surgery.
It’s not clear how long Mbappe will be sidelined for but he’s likely to be a major doubt for France’s next outing, which sees them face the Netherlands on Friday night, live on talkSPORT.
After receiving a lengthy spell of treatment, Mbappe was forced off the pitch, as is customary for any player who requires medical intervention.
However, Mbappe picked up a booking for re-entering the field of play without the referee’s permission – something that was a very deliberate time-wasting effort as he burst onto the pitch before slumping to the floor once again.
Reacting to the incident, Roy Keane told ITV: “He’s got an injury and he’s gone back on the pitch to try and stop the play, but he’s gone to sit on the pitch.
