Manchester United forward Anthony Martial left training after just four minutes on Thursday morning.
The Frenchman was pictured arriving at the club's Carrington base in his Mercedes G Wagon at 8.55am but then snapped driving back out shortly afterwards at 8.59am.
Erik ten Hag is preparing his players for Saturday's return to Premier League action against Brighton at Old Trafford.
Martial, 27, started United's last two matches - the 3-2 win over Nottingham Forest and the 3-1 defeat to Arsenal prior to the international break.
