There has been plenty of debate over the future of a number of Pedro Caixinha's summer signings after the Portuguese boss was given his marching orders by the Rangers hierarchy last week.
Caixinha's agent Nuno Batista has even leapt to the defence of duo Carlos Pena and Eduardo Herrera, telling the Scottish Sun that the Mexican stars are not to blame despite their poor form and expensive transfer fees.
According to bookmakers Paddy Power, Aberdeen boss Derek McInnes remains strong favourite to take over at Ibrox and it will be interesting to see what the former Bristol City manager would do with Caixinha's signings if appointed.
It is obvious that the 46-year-old boss goes about his transfer business differently to Caixinha, signing five players for Aberdeen this summer of which four had had previous Scottish Premiership experience. The other signing, Nicky Maynard, played under McInnes at Bristol City.
Of Caixinha's 11 summer deals, only two boasted previous top-flight experience north of the border and it can be argued that Rangers' influx of players lacked the knowledge required to hit the ground running in Scottish football.
If McInnes does take over at Rangers then, preference is likely to be given to players who are proven Scottish Premiership performers, and that could also see him recall Michael O'Halloran in January from St. Johnstone.
It was plain to see that O'Halloran and Caixinha did not see eye to eye, but if McInnes does become Caixinha's successor, it is likely that he will be given much more of a chance under someone who has also managed St. Johnstone.
The 26-year-old has scored five goals in nine league outings this season and that proven Scottish Premiership form is desperately required in the Rangers side, something which McInnes will look to install at Ibrox.
A McInnes appointment at Auchenhowie then would surely save what ever is left of O'Halloran's Rangers career, that is, if the uncapped Scotsman wants to return to Glasgow.
