A new investigative report has revealed how Anthony Martial's goal in Manchester United's comeback win over Newcastle on Saturday cost the premiership club millions of pounds.

Manchester United's comeback win over Newcastle was exactly what they needed to boost morale on the pitch, but it cost them millions off it, according to Dailymail UK
United battled back after falling 2-0 down at Old Trafford inside 10 minutes, scoring three times in the final 20 minutes to win 3-2.
Anthony Martial curled a superb effort into the bottom corner for the equaliser, between Juan Mata's free-kick and Alexis Sanchez scoring the winner with his head.
That goal by the French forward cost United £7.7million, thanks to a clause in the deal which saw him move from Monaco in 2015.
United parted with £38.5m in two installments to sign Martial, but the deal included plenty of lucrative bonuses which meant it could have eventually cost as much as £61.6m.
One was that United agreed to pay Monaco an extra £7.7m if the Frenchman netted 25 goals in the Premier League before the end of the current 2018-19 season.
Monaco were waiting on the cash for 10 months - before Martial struck against Newcastle, his last league goal had come against Burnley in January.
However the goal count eventually ticked over to 25 on Saturday - and it may not be the last time United have to pay up.
There are two more clauses in Martial's contract that can be triggered which would see United have to fork out another £7.7m each.
One of these requires him to make 25 appearances for France - he is currently eight away - while the other would need him to win the Ballon D'Or.
That means United have so far paid Monaco £46.2m for the 22-year-old - and could be looking to recoup some of that fee soon, unless Martial's relationship with manager Jose Mourinho improves soon.
Martial and Mourinho fell out over the summer when he left the US tour to be with his wife and new baby. He was fined two weeks' wages.
A sale would suit Monaco however - they are due 50 per cent of any fee United receive, thanks to a sell-on clause inserted in the transfer.
