Every single window at Old Trafford is being covered in clear anti-shatter film to protect players, staff and fans in the event of an explosion in or around the ground.

The move comes as Manchester United ramp up security in the wake of last year's Paris terror attacks, with the installation of the sheets at their stadium designed to prevent glass smashing.

Workmen are this week making sure each and every window pane has the film attached - a huge job given the amount of glass utilised around the stadium.

Supporters are already being given full body searches as they embark on Old Trafford on matchdays, a procedure which came in after the Paris atrocities in November in which 130 innocent people lost their lives.

The Stade de France was targeted by ISIS fanatics, who had planned to gain entry to the ground and detonate bombs, but, luckily, were thwarted from entering the stadium.

All fans watching Louis van Gaal's side are patted down on matchday entry after being given a full scan and some staff and supporters are also being asked to remove their coats in specific sections of the ground.

The new security measures were rolled out for the Champions League draw against PSV Eindhoven, a fortnight after events in the French capital.

They have continued since, with heightened security around the perimeters of Old Trafford to keep the thousands descending on the ground safe in any eventuality.

Louis van Gaal admitted what happened in Paris previously left some of his players traumatised

United boss Louis van Gaal revealed the experience of that night in Paris had left a number of his players feeling traumatised.

The match between France and Germany continued, despite explosions being clearly audible in the stadium during the friendly game between France and Germany.

Midfield pair Morgan Schneiderlin and Bastian Schweinsteiger were among those involved in the match.

And thousands of fans flocked on to the playing field at full time, scared of heading home as the horrific scenes unfolded in the French capital which left so many dead and wounded.

Van Gaal said: 'What they have told me is private I think, but we have communicated about it.

'I think it is, for every human being in this world, a big blow, so I don't think I have to mention what our discussions were.'
