Steven Gerrard has been warned by Rangers icon Ally McCoist that even Pep Guardiola and Jose Mourinho would struggle to make a mark at Ibrox.
Rangers have, however, endured a testing period over recent years, with financial struggles leading to a humbling fall from grace for a once dominant outfit.
McCoist fears that those issues remain in Glasgow and that Gerrard would be taking on the kind of challenge that would test proven performers at Manchester rivals City and United to the fullest.
The former Gers striker told talkSPORT: “You could give it to [Pep] Guardiola, [Jose] Mourinho, Steven Gerrard… If [Rangers] don't get the money to get better quality players, they will continue to finish second behind Celtic. That is the bottom line.
“I have heard people make comparisons to 1986 when Graeme Souness took his first manager's job but the only comparison I can see is they are both former Liverpool greats.
"When Graeme came to Rangers, he played and was absolutely sensational. And he was backed in the transfer market. Two of his first three signings were England captain Terry Butcher and the England goalkeeper Chris Woods. That is where the similarity ends.
"Put it this way, I don't think Steven Gerrard will get the financial clout to go out and buy the England captain."
Souness, another Liverpool icon, took a player-manager post at Rangers in 1986.
He guided the club to three league titles and four Scottish League Cup triumphs, but was working under markedly different conditions to those currently seen at Ibrox.
Graeme Murty still as the Gers in contention for a runner-up finish in the Scottish Premiership this season, but the club are destined to finish a long way back on treble-chasing arch-rivals Celtic.
