Romelu Lukaku got Manchester United off to a dream start against PSG in their Champions League second leg with a goal after just one minute and 51 seconds.

Before some fans had even taken their seats Lukaku pounced a mistake in the PSG defence, before rounding Gianluigi Buffon and sliding the ball into the net from a tight angle.

The goal was the fastest by a United player in a Champions League knockout match since Wayne Rooney scored against Bayern Munich after only 63 seconds in 2010, according to Opta.

United went on to lose that tie, but took hope from Lukaku's early strike in Paris as they reduced their aggregate deficit to trail 2-1.
