Chelsea owner Todd Boehly has been slammed by Al Mokawloon director Mohamed Adel Fathi for his comments about Mohamed Salah coming from the Blues academy.
Salah started his career at the Cairo-based team after spending four years in the club's academy between 2006 and 2010.
The Egyptian attacker went on to play 38 league games for the club, scoring 11 goals before moving to Swiss side Basel in 2012.
It was his form at Basel that earned him the move to Chelsea in 2014, when he was 21-years-old, so making the claim that he came from the Chelsea academy 'shows a lack of understanding', according to Adel Fathi.
He said in a Facebook post, via GOAL: 'What the new owner of Chelsea says shows a lack of understanding.
'Mohamed Salah is a source of pride for the Al Mokawloon Club and Egyptian and Arab football, and we are honoured that he is one of our sons.
'The whole world knows Salah's career and how he started with us, but it seems that the owner of Chelsea is the only person in the world who is ignorant of this information.'
Salah failed to prove himself at Chelsea and was eventually loaned out to Serie A sides Fiorentina and Roma, with the latter opting to buy him from the Blues.
During his time in Italy's capital, Salah re-discovered his best form which earned him a move back to the Premier League with Jurgen Klopp's Liverpool.
Since the move to the Reds, Salah has gone onto to become one of the most prolific players the league has ever seen, scoring 120 goals in 186 games in England, as well as winning the Premier League and Champions League.
Boehly made the claim at the SALT forum in New York as he was praising his newly acquired club's youth academy, suggesting that it deserves credit for developing stars such as Salah and Belgian international and Genk academy product Kevin De Bruyne, as well as Cobam talents such as Mason Mount and Tammy Abraham.
He told SALT: 'We have one of the best academies in the world.
'If you look at what our academy has developed, our academy is Mo Salah, Kevin De Bruyne. More recently, Tammy Abraham, Reece James, Mason Mount, Trevoh Chalobah.'
