Tottenham loanee Randal Kolo Muani has reportedly been training in a specially fitted mask ahead of the north London derby against Arsenal. During Spurs’ 2-2 draw with Manchester United earlier this month, the striker suffered a fractured jaw following a clash with Harry Maguire. However, after the Paris Saint-Germain man did not need to have surgery, Tottenham are doing all they can to give him a chance of facing the Gunners this weekend.
