As Crystal Palace continue their bid to avoid relegation, midfielder Yohan Cabaye got through a high-tech workout on Monday.
The French midfielder, who did not feature in the Eagles' 2-0 defeat by Burnley last Saturday, donned an oxygen deprivation mask and and EMS (Electric Muscle Stimulation) kit during his workout.
The 31-year-old last featured for Sam Allardyce's side in their 1-0 loss against Tottenham earlier this month.
Cabaye replaced James McArthur in the 64th minute of that defeat at Selhurst Park.
