A serious ankle injury suffered by Luke Shaw marred Manchester United's return to Champions League action against PSV on Tuesday.

Shaw went down after a challenge from PSV's Hector Moreno as he burst into the PSV area in the 15th minute of the Group B opener at the Philips Stadion, with replays showing his right ankle apparently breaking under the impact.

The England left-back received oxygen on the pitch before being taken off on a stretcher following a delay of around nine minutes.

Marcos Rojo replaced Shaw, with the game goalless at the time of the injury.
