Allan, 23, has already made the move to England once, joining West Bromwich Albion from Dundee United in January 2012, but failed to make an impression with the Baggies, eventually moving back to Scotland with Hibernian just a year ago.
The midfielder has now rebuild his reputation under Alan Stubbs, playing a key role as Hibs made it to the Scottish Championship play-offs, only to lose at the hands of Rangers.
Now though, his impressive displays at Easter Road have triggered interest in his services, with the BBC reporting last week that Old Firm rivals Celtic and Rangers have both made enquiries over Allan's availability.
With just one year left on his contract at Hibernian, Allan could well be sold this summer if an enticing offer comes in - and now, Ipswich have joined the race for his signature.
The Tractor Boys have hit a cash windfall having sold left back Tyrone Mings to Bournemouth, and the Daily Record report that Mick McCarthy's men are keen to spend a chunk of their money on Allan in order to beat Celtic and Rangers to the punch.
England or Scotland?
Allan could be forced to choose between a move back south of the border again, or the chance to stay in Scotland should Ipswich, Celtic and Rangers all pursue him.
Having already struggled in England once, Allan may be reluctant to make the move down to England so soon after leaving West Brom, which could play into the hands of Celtic and Rangers.
Continuing to develop in Scotland with either Celtic, Hibernian or Rangers is the best plan for Allan right now, but given his impressive performances for Hibernian, it seems like only a matter of time before he does end up in English football once again.
