Date of birth
Fiery Scot O'Brien has been a key figure in our midfield since becoming Neal Ardley's first permanent Notts signing when he joined from Bradford in January 2019.
The experienced midfielder endured a torrid time with injuries last season, suffering a double fracture and dislocation of his arm away to Bromley before sustaining a deep gash to his leg in his comeback match against Chesterfield in the FA Trophy.
He returned to action in the new year, however, and is set to be an important player for us once again in 2020-21.
O'Brien came through the ranks at Celtic and had spells with Dunfermline Athletic, Dundee United and Motherwell before moving south of the border with Barnsley.
He spent four seasons at Oakwell ahead of a switch to Coventry, where he made 70 appearances.
O’Brien had spells with Shrewsbury Town and Ross County before joining Bradford for the first half of 2018-19.
And he committed himself to Notts for the rest of the campaign, citing Ardley's keenness to sign him as a big factor in his decision before going on to pen a new contract the following summer.
