ABU DHABI — Dr Mark Waller, who has more than two decades of experience at Liverpool FC, has been appointed medical services director at the Al Jazira Club. In the role, he will lead a team of 23 staff in looking after all aspects of medical care at the club – from injury prevention, through to nutrition and the rehabilitation of injured players.
Dr Waller joins the club in the run up to the new season and is working closely with the first team coaches to bring added benefits to the squad.
In the coming weeks and months his brief will expand to include the youth academy and those involved in all sports and in all age groups at the club.
He was recruited by the board of directors at Al Jazira Club after they decided the prevention and treatment of injuries needed to be a priority.
“I spent 21 years at Liverpool Football Club and gained a lot of experience in that time,” said Dr Waller"
I assume he's still there.
