Celtic are interested in Everton striker James Vaughan.
The Daily Mail says Celtic have joined Cardiff City in their pursuit of Vaughan.
Vaughan has been informed of Celtic's interest and is keen to make the move to the SPL in the hope of kick-starting his career.
Cardiff have been persistently linked with a player who became the youngest-ever Premier League goalscorer at the age of 16 before succumbing to a run of injuries.
