Frank de Boer's comments on Marcus Rashford appear to have rattled Manchester United's social media just as much as Jose Mourinho after they published supposed proof that the Dutchman was talking rubbish.
That proof comes in the form of a statistic which claims Rashford has made more Manchester United appearances than any other player since Mourinho took charge at the start of the 2016-17 season.
The 20-year-old has played a part in 93 games as both a starter and from the substitutes bench, 12 more than the second highest appearance maker David de Gea (81) and 13 ahead of outfield stars Ander Herrera and Anthony Martial (80).
Manchester United manager is apparently not stalling the development of Marcus Rashford
Manchester United tried to prove that Rashford was playing a lot of football under Mourinho
The former Crystal Palace manager told BT Sport that it is 'a pity' Rashford plays under Mourinho after the England international marked his first league start of the year with both goals against Liverpool.
Those words incurred the wrath of Mourinho, who dubbed De Boer the 'worst manager in Premier League history' and now the club have come to their manager's aid with the supposed 'myth-busting stat'.
However, the accompanying article neglects to mention just how many of Rashford's 93 games have come from the bench. Indeed, 29 of his 59 Premier League appearances under Mourinho have been as a substitute.

As a result, out of a possible 5,310 minutes that he could have played in those 59 games, Rashford was on the pitch for just 3,147 of them, which accounts for under 60 per cent.
It gets even worse in the Champions League, where Rashford has played a part in seven games, but started just two of them. Overall, he has played only 255 minutes out of a possible 630, well under 50 per cent.
Of course, Manchester United's claim ignores the fact that a player is awarded with an appearance whether they play the full 90 minutes or just one. While he may be a prominent figure in the team, he is far from the key player the headline stat suggests.
