According to the BBC, both Celtic and Rangers have made enquiries about signing Hibernian midfielder Scott Allan - but manager Alan Stubbs has told Sky Sports that he isn't worried.
Celtic have brought in just one summer signing so far in Manchester City defender Dedryck Boyata, whilst Rangers have just landed two centre backs themselves, snapping up Danny Wilson and Rob Kiernan earlier this week.
Now, it seems that both Ronny Deila and Mark Warburton will turn their attentions to strengthening their midfield options, with Allan a reported target.
The BBC report that the Old Firm rivals have both contacted Hibernian over signing the 23-year-old midfield, but no bids have been made yet.
Allan was integral in Hibernian's run to the Scottish Championship play-offs last season, but they now risk losing the former Dundee United man, with his contract set to expire in 2016.
As a result, Hibs manager Alan Stubbs - who played for Celtic - has told Sky Sports that he is comfortable with Allan's situation, even though he acknowledged teams could bid to sign him.
"There are no bids that I know of," Stubbs said. "Scott Allan is a Hibs player and I don't see any reason why that should change. Scott has one year left on his contract and we as a club are comfortable with the situation. We can't stop teams from putting bids in, but we are not welcoming them at all," he added.
Celtic have the upper hand
If the two Old Firm rivals go head to head for Allan's signature, then it's clear that Ronny Deila's Bhoys would be favourites to land him.
Deila can offer a title challenge in the top flight rather than the second tier of Scottish football, whilst the lure of the Champions League would also be a huge factor.
Celtic would also have the upper hand over Rangers financially, making it difficult to see Allan signing for Rangers - unless Celtic pull out of the race.
