Celtic winger Scott Allan has joined Championship side Rotherham on a season-long loan deal, it was announced on Thursday.

The Hoops confirmed on their official Twitter account that the 24-year-old would be joining the English second-tier side for the season.

The Glasgow-born youngster will join Alan Stubbs’ side as they prepare to open their campaign against Wolves at home on Saturday.

The new Millers boss and former Everton defender worked with Allan when the two were at Hibernian together for the 2014-15 season. The 44-year-old manager also used his Celtic connections after a five-year spell at the club during his playing career.

Allan only moved to the Hoops last summer, but after just 17 appearances, just three of which were starts, the former Scotland Under-21 international has left for more game time.

Although he is just 24-years-old Allan has also already played for four other English sides after moving to West Brom in 2012 before loan spells at Portsmouth, MK Dons and Birmingham.

The winger still has three-years left on his Hoops contract and Rotherham have became his ninth different club after making his professional debut six years ago.

Allan has made 110 appearances scoring eight goals over the duration of his career.
