What did the former Rangers coach have to say about the Ibrox winger?
Murphy signed on a permanent basis for Rangers in the same summer that Gerrard arrived after a successful loan spell. However, his 2018/19 season was wrecked by injury and he's only now getting back to match fitness.
After a long battle, he came off the bench during the 5-0 win over Hamilton on Sunday, to a big reception from supporters.
Now Black, who has worked extensively with Murphy throughout his career, thinks the attacker is set to stake a claim for more action.
As quoted by The Scottish Sun, he said: "Murphy is another positive asset for the manager to call upon. He has so much to offer and if he can find his best level again then he will be like a new signing.
"Rangers have plenty wingers in their squad, but so many of them seem to be injured right now.
"There is an opening there and my money would be on Murph making the most of it."
What next for Murphy?
As Black notes, the Gers are suffering from a number of injury problems right now. Jordan Jones, Ryan Kent and Brandon Barker have all been on the sidelines of late.
That gives Murphy a massive chance to get more action under his belt after the international break. Another week training at Auchenhowie will do his return no harm at all and he should be raring to go when the Scottish Premiership returns.
With six goals and 13 assists in 26 appearances for Rangers, he has a decent record. That Gerrard has kept him around through squad culls speaks volumes about what the Gers boss thinks of him.
He has every chance of making the kind of impact Black describes.
