The 26-year-old has spent the campaign on loan with Hibernian and said to the Edinburgh Evening News that he longs for a permanent deal this summer.
“Yes. If we can keep this squad together and everything else goes well it will basically come down to how the Hibs and Celtic hierarchies deal with it, it’s not up to me.
“But I love it here. In my last month at Dundee I was back fit and starting to tick again. But this came up at the time and I was fortunate to get it done.”
Allan initially joined Celtic from Hibernian in 2015 and has gone on to make just 17 appearances in all competitions.
The Scottish u21 international struggled for playing time with the Hoops which led to a series of loan spells just one year after signing.
He spent time with League One side Rotherham United (August 4,2016 – May 31, 2017), Scottish Premiership side Dundee FC (July 1, 2017 – January 30, 2018) and Hibs (January 31, 2018 – present).
Given the midfielder’s last Celtic appearance was all the way back in July 2016, his future may be away from Parkhead.
Nevertheless, it’s a blow that a player’s been unable to fulfil his potential with the Hoops and manager Brendan Rodgers said he will weight up all options at the end of the season.
“I haven’t gone that far. It is a big month ahead for us and a big four games, so I will revisit that at the end of the season.”
Hibernian are currently fourth in the Scottish Premiership with 62 points from 34 games this season, coming off the back of seven wins and three draws from their last 10 outings.
