Rangers fans have responded playfully, it seems, to suggestions there could be new director of football in place at Ibrox.
In his new role, Allen would be expected to assist with Rangers' summer recruitment drive, which is already well underway following the signings of Bruno Alves, Ryan Jack, Fabio Cardoso, Dalcio and Daniel Candeias by manager Pedro Caixinha.

It's plausible, then, to think a number of City youngsters could feature in the new man's Ibrox plan. And Rangers fans have naturally been speculating as to who those players might be, with one particular name - already a familiar one in Glasgow - recurring.
Here's what the Light Blues fans are saying...
Mark Allen of Man City as DOF that adds substance to the Partick Roberts loan deal. Offft that wouldn't go down well.— Gregco (@Gregco5088) 14 June 2017
Heard a rumour that Mark Allen from mancity been appointed as D.O.Fat Rangers not sure about this Patrick Roberts he's bringing with him— Tam Smib (@SmibTam) 14 June 2017
I hear that Patrick Roberts is no too bad— James (@jamesablack) 14 June 2017
Roberts, of course, has spent the past 18 months at Rangers' Old Firm rivals Celtic, and is wanted back at Parkhead by manager Brendan Rodgers.

But with Allen on board or not, it would be some surprise to see Roberts turn out for any Glasgow club except for the Bhoys next season.
