The 23-year-old is recovering in the London Chest Hospital after collapsing on the pitch before halftime in the game at White Hart Lane.
Doctors said the player had made a miraculous recovery after being “in effect dead” for 78 minutes as they battled to restart his heart with 15 defibrillator shocks.
