Riordan has struggled to break into the Celtic first-team

Celtic striker Derek Riordan could seal a move to Championship side Burnley before the end of the week.

Burnley boss Owen Coyle failed with a £400,000 bid for the former Hibernian player in January and is keen to capture the 25-year-old this summer.

No new bid has been made but an agreement could be reached before Celtic begin pre-season training.

Riordan has made a total of 32 appearances since joining Celtic in 2006, scoring eight goals.
