The Rangers manager was speaking after his side's win against Hibernian at Ibrox.
The Ibrox side were in sensational form on Sunday, thrashing Hibs 6-1 to make it two wins from two at the start of their Scottish Premiership campaign.
With Defoe and Morelos both on the scoresheet again, Gerrard really is spoilt for choice when it comes to selecting forwards.
However, the Kyle Lafferty exit means the club there's a lack of specialised back-up to the duo. There's an argument the Gers need a third man to compete for the position.
Gerrard opened up the possibility in his post-match comments, telling The Scotsman: "We are going to need both of them firing if we are to have any ambitions of moving forward.
"There is also a debate that we may need to get a third striker, even though we have other options who can play there."
Room for another?
Gerrard's comments certainly keep the transfer fire burning for Rangers and their supporters as the end of the summer transfer window approaches.
The club have secured nine players so far since the end of last season.
Ranging from a permanent contract for last season's loan man Steven Davis to millions invested in Filip Helander, Gerrard and his recruitment deal have done their business early.
The Ibrox boss spoke over the weekend about the incoming business at Rangers being 99.9% done, leaving open the possibility of yet another signing if the right player came along or someone is sold.
Is a striker needed?
Morelos and Defoe have already scored a magnificent 12 goals between them at the start of 2019/20 season.
However, if either of the duo get injured or are suspended for a lengthy amount of time, it could leave Rangers short in terms of depth and support.
Greg Stewart is also at the club and he's likely the other option Gerrard speaks of in his comments above. More of a creative option than an instinctive finisher though, is he a viable choice to play as a central striker?
A third specialist striker would be ideal if Rangers can afford it and the Ibrox boss can justify it to his board.
It may even open up a bit of tactical flexibility for Gerrard, with the option of playing two forwards on a regular basis becoming more viable.
