Arsenal are in a fight to keep their head of medical services Gary O'Driscoll.
The highly respected member of their staff is a target for Liverpool, per The Daily Mail.
The Reds are about to lose Andrew Massey, who is set to take up a role with FIFA.
It means they are on the lookout for a replacement, and O'Driscoll is at the top of their list.
He is said to be the best in his field and Arsenal do not want to lose him.
Such a departure would be a blow for recently appointed boss Mikel Arteta.
While he may be well paid at Arsenal, O'Driscoll may want to work at a more successful team in Liverpool.
He also has roots in the north-east, having worked in Manchester in the 2000s.
O'Driscoll has been with Arsenal since 2009.
