The duo, who overhauled the Merseyside giants' ailing youth system and helped numerous youngsters graduate to the first-team squad, have left Anfield in a surprise move
McParland and Borrell were popular and key figures in the revival of the Reds' youth system in recent years and their departures have shocked players and staff.
In his role as academy director McParland helped overhaul the club's ailing development system and played a significant personal role in attracting Raheem Sterling to the club from QPR in February 2010.
Borrell joined Liverpool in July 2011 after spending 13 years with Barcelona, during which time he worked with the likes of Lionel Messi, Gerard Pique and Cesc Fabregas.
The Spaniard coached the Reds' Under-18 and Under-21 sides and oversaw their maiden NextGen Series campaign before taking up the role of head of academy coaching.
During their time at the club, the pair helped the likes of Sterling, Andre Wisdom, Suso, Conor Coady and John Flanagan break into the first-team squad.
Liverpool declined to comment when contacted by Goal.
