Martial two goals away from costing Manchester United €10m more

Signed initially for €60 million from Monaco, the attacker's fee could rise as high as €90m, with the first of three lucrative bonuses nearing for the Ligue 1 side.

Anthony Martial is two goals away from costing Manchester United another €10 million as a clause in his transfer agreement will be triggered.

The France international forward has been in hot form for the Red Devils of late, scoring four times in his last six outings, working his way closer to the forefront of manager Jose Mourinho’s plans.

But when he reaches the milestone of 25 goals for the club – something he is only two strikes away from doing – the Old Trafford outfit will have to stump up another €10m to Monaco, according to documents obtained by Football Leaks back in January 2016.

The 21-year-old forward arrived from the Ligue 1 outfit in the summer of 2015 with little reputation in England, so his fee of €50 million seemed extravagant at the time.

However, the attacker, who has been likened to Thierry Henry, quickly made a positive impression by scoring 17 goals in England during his first season – including a superb winner against Liverpool only weeks after arriving.
