Scott Allan is set to move to Rotherham on a season-long loan from Celtic, according to Sky sources

Celtic midfielder Scott Allan is set to sign for Rotherham United on a season-long loan deal, according to Sky sources.

The move will see Allan reunited with his former Hibernian boss Alan Stubbs, who left Easter Road at the end of the season.

Allan, who will become Stubbs' sixth signing of the summer, agreed a four-year deal with Celtic in August last year after Hibs rejected three bids from Rangers.

Alan Stubbs signed Allan when he took over at Hibernian

However, he only started three times and made just 17 appearances in total during the season, and now finds himself well down the pecking order in a Celtic squad with numerous midfield options.

The 24-year-old started his career with Dundee United before a move to West Brom in 2012 but he was sent out on loan after failing to break into the first team.

Stubbs took Allan back to Scotland in July 2014 after he was released by the Baggies.

Rotherham have also completed the signing of Kelvin Wilson

Rotherham have also completed the signing of another former Celtic player in Kelvin Wilson, subject to EFL and FA ratification.

The 30-year-old has signed a one-year contract with the club after successfully undergoing a medical.

Wilson, who was at Nottingham Forest last season, will join up with his new team-mates on Wednesday morning ahead of their opening Sky Bet Championship fixture against Wolves on Saturday.
