Champions League round-up: Manchester United flew home clutching a priceless 1-0 Champions League lead and left behind a storm of controversy that included a furious Lille coaching staff, who attempted to haul their players off the pitch before the final whistle.
Lille keeper Tony Sylva was still lining his wall up when Ryan Giggs calmly stroked his free-kick into the top corner seven minutes from time.
The home players raced to Dutch referee Eric Braamhaar, clearly unable to comprehend how the official had allowed the goal to stand.
But Braamhaar was not for turning and triggered a quite stunning reaction from the home bench, with the signal clearly going out for the Lille players to head to the sideline and end the game.
Thankfully, sanity prevailed and the contest continued, allowing United to claim a victory in a game which, until those bizarre last few minutes seemed set to be remembered for the chilling security scare inside the visitors end where fans seemed to get crushed in front of a 10 foot barrier.
Mercifully, no-one was injured in the incident, although that was hardly due to the actions of the riot police, who fired tear gas into the enclosure.
In Holland, Arsenal's hopes of progressing towards a second successive final suffered a knock-back tonight as they lost 1-0 at PSV Eindhoven.
The Gunners never really hit top gear in the Philips Stadion, where chances were at a premium.
In the end, it was a fine long-range effort from Ecuador midfielder Edison Mendez on the hour which settled matters - and gave the Dutch league leaders a slender advantage to take back to Emirates Stadium in a fortnight's time.

Celtic had to produce all their battling qualities to hold AC Milan to a goalless draw at Parkhead. In an open and entertaining game, Italy World Cup star Alberto Gilardino had several chances to put the classy visitors ahead but the Hoops, who never really threatened, survived with their goal intact.
The Bank of Scotland Premier League champions may need to score at least once in the San Siro in a fortnight if they are to reach the quarter-finals of the competition for the first time.
